1.6.3 Safety actionThis is a summary of conditions and actions toprevent injury to personnel and damage to theenvironment and to equipment.

NEVER DO MAINTENANCE WORKWHEN THE UNIT IS CONNECTED TO POWER(Lock Out)

DRAIN THE PUMP AND ISOLATE PIPEWORKBEFORE DISMANTLING THE PUMPThe appropriate safety precautions should be takenwhere the pumped liquids are hazardous.

FLUOROELASTOMERS (When fitted.)When a pump has experienced temperatures over250 ºC (482 ºF), partial decomposition offluoroelastomers (example: Viton) will occur. In thiscondition these are extremely dangerous and skincontact must be avoided.

HANDLING COMPONENTSMany precision parts have sharp corners and thewearing of appropriate safety gloves and equipmentis required when handling these components. To liftheavy pieces above 25 kg (55 lb.) use a craneappropriate for the mass and in accordance withcurrent local regulations.

NEVER OPERATE THE PUMP WITHOUT THECOUPLING GUARD AND ALL OTHER SAFETYDEVICES CORRECTLY INSTALLED

GUARDS MUST NOT BE REMOVED WHILETHE PUMP IS OPERATIONAL

THERMAL SHOCKRapid changes in the temperature of the liquid withinthe pump can cause thermal shock, which can resultin damage or breakage of components and should beavoided.

NEVER APPLY HEAT TO REMOVE IMPELLERTrapped lubricant or vapor could cause an explosion.

HOT (and cold) PARTSIf hot or freezing components or auxiliary heatingequipment can present a danger to operators andpersons entering the immediate area, action must betaken to avoid accidental contact (such as shielding).If complete protection is not possible, the machineaccess must be limited to maintenance staff only withclear visual warnings and indicators to those enteringthe immediate area. Note: bearing housings must notbe insulated and drive motors and bearings may behot.

If the temperature is greater than 68 °C (175 °F) orbelow 5 °C (20 °F) in a restricted zone, or exceedslocal regulations, action as above shall be taken.

PREVENT EXCESSIVE EXTERNALPIPE LOADDo not use pump as a support for piping. Do notmount expansion joints, unless allowed by Flowservein writing, so that their force, due to internal pressure,acts on the pump flange.

ENSURE CORRECT LUBRICATION(See section 5, Commissioning, startup, operationand shutdown.)

NEVER EXCEED THE MAXIMUMDESIGN PRESSURE (MDP) AT THETEMPERATURE SHOWN IN 3.4.4See section 3 for pressure versus temperatureratings based on the material of construction.

NEVER OPERATE THE PUMP WITHTHE DISCHARGE VALVE CLOSED(Unless otherwise instructed at a specific point in theuser instructions.)(See section 5, Commissioning start-up, operationand shutdown.)

NEVER RUN THE PUMP DRY ORWITHOUT PROPER PRIME (Casing Flooded)

NEVER OPERATE THE PUMP WITHTHE SUCTION VALVE CLOSEDIt should be fully opened when the pump is running.

NEVER OPERATE THE PUMP ATZERO FLOW OR FOR EXTENEDED PERIODSBELOW THE MINIMUM CONTINUOUS FLOW

THE PUMP SHAFT MUST TURNCLOCKWISE WHEN VIEWED FROM THE MOTORENDIt is absolutely essential that the rotation of the motorbe checked before starting the pump.

HAZARDOUS LIQUIDSWhen the pump is handling hazardous liquids caremust be taken to avoid exposure to the liquid byappropriate pump placement, limiting personnelaccess and by operator training. If the liquid isflammable and/or explosive, strict safety proceduresmust be applied.

1.8 Noise levelWhen pump noise level exceeds 85dBA attentionmust be given to prevailing Health and SafetyLegislation, to limit the exposure of plant operatingpersonnel to the noise. The usual approach is tocontrol exposure time to the noise or to enclose themachine to reduce emitted sound. You may havealready specified a limiting noise level when theequipment was ordered, however if no noiserequirements were defined then machines above acertain power level will exceed 85dBA. In suchsituations consideration must be given to the fitting ofan acoustic enclosure to meet local regulations.

Pump noise level is dependent on a number offactors - the type of driver, the operating capacity,piping design and acoustic characteristics of thebuilding.

If a pump unit only has been purchased, for fittingwith your own driver, then the "bare pump" noiselevels from the table should be combined with thelevel for the driver obtained from the supplier. If themotor is driven by an inverter, it may show anincrease in noise level at some speeds. Consult aNoise Specialist for the combined calculation.

1.8.1 D-814 bare pump noise level informationBelow is a tabulation of sound pressure readings forframe mounted D-814 pumps for general informationand not to be subject to guarantee by Flowserve.Tests were conducted in accordance with theStandards of the Hydraulic Institute, 13th Edition,1975. Pumps were tested in a spacious room(simulating an open field) with driver covered by asound absorbing enclosure and with system valves,venturi’s, and tanks behind a sound absorbing wall.Decibel readings do not include driver or systemnoise. Pumps were tested through a normal operatingrange of about 75% to 125% of the best efficiencypoint at all impeller diameters.

2 TRANSPORT AND STORAGE

2.1 Consignment receipt and unpackingImmediately after receipt of the equipment it must bechecked against the delivery/shipping documents forits completeness and that there has been nodamage in transportation. Any shortage and/ordamage must be reported immediately to FlowservePump Division and must be received in writing withinone month of receipt of the equipment. Later claimscannot be accepted.

Check all crates, boxes or wrappings for anyaccessories or spare parts that may be packedseparately from the equipment or attached to sidewalls of the box or equipment.

Each product has a unique serial number. Checkthat this number corresponds with that advised andquote this number in correspondence as well aswhen ordering spare parts or further accessories.

2.2 HandlingBoxes, crates, pallets or cartons may be unloadedusing fork-lift vehicles or slings depending on theirsize and construction.

2.3 Lifting

Pumps and motors often haveintegral lifting lugs or eye bolts. These are intendedfor use in only lifting the individual piece ofequipment.

Do not use eye bolts or cast-in liftinglugs to lift pump, motor and baseplate assemblies.

To avoid distortion, the pump unitshould be lifted as shown.

Care must be taken to liftcomponents or assemblies above the center ofgravity to prevent the unit from flipping.

Lifting bare pumpHorizontal Pumps: Sling around the pump dischargenozzle and around the outboard end of the bearinghousing with separate slings. Choker hitches mustbe used at both attachment points and pulled tight.Make sure the completion of the choker hitch on thedischarge nozzle is toward the coupling end of thepump shaft as shown in Figure 2-1. The slinglengths should be adjusted to balance the loadbefore attaching the lifting hook.

A crane must be used for all pump sets inexcess of 25 kg (55 lb.). Fully trained personnelmust carry out lifting in accordance with localregulations.

Lifting pump, motor and baseplate assemblyHorizontal: If the baseplate has lifting holes cut inthe sides at the end, insert lifting S hooks at the fourcorners and use slings or chains to connect to thelifting eye as shown in Figure 2-1. Do not use slingsthrough the lifting holes.

For other baseplates, sling around the pumpdischarge nozzle, and around the outboard end ofthe motor frame using choker hitches pulled tight(Figure 2-1).

The sling should be positioned so the weight is notcarried through the motor fan housing. Make surethe completion of the choker hitch on the dischargenozzle is toward the coupling end of the pump shaftas shown in Figure 2-1.

2.4 Storage

Store the pump in a clean, drylocation away from vibration. Leave flange covers inplace to keep dirt and other foreign material out ofpump casing. Turn the pump shaft at regularintervals to prevent brinelling of the bearings and theseal faces, from sticking.

The pump may be stored as above for up to 6months. Consult Flowserve for preservative actionswhen a longer storage period is needed.

Short term storageNormal packaging is designed to protect the pumpand parts during shipment and for dry, indoorstorage for up to six months or less.

Normal packaging:a) All loose unmounted items are packaged in a

water proof plastic bag and placed under thecoupling guard. Larger items are boxed andbanded to the baseplate. For pumps notmounted on a baseplate, the bag and/or box isplaced inside the shipping container.

b) Flange covers are secured to both the suctionand discharge flanges.

c) Assemblies ordered with external piping, insome cases components may be disassembledfor shipment.

2.5 Recycling and end of product lifeAt the end of the service life of the product or itsparts, the relevant materials and parts should berecycled or disposed of using an environmentallyacceptable method and in accordance with localregulations. If the product contains substances thatare harmful to the environment, these should beremoved and disposed of in accordance with currentlocal regulations. This also includes the liquidsand/or gases that may be used in the "seal system"or other utilities.

Make sure that hazardous substances aredisposed of safely and that the correct personalprotective equipment is used. The safetyspecifications must be in accordance with thecurrent regulations at all times.

4 INSTALLATION4.1 Cleaning prior to installationClean suction and discharge flange surfaces orpipe connections. If any debris has entered themotor through fan or cooling openings, remove it.

4.2 LocationThe pump should be located to allow room foraccess, ventilation, maintenance, and inspectionwith ample headroom for lifting, and should be asclose as practical to the supply of liquid to bepumped.

4.3 Part assembliesThe supply of motors and baseplates are optional.As a result, it is the responsibility of the installer toensure that the motor is assembled to the pumpand aligned as detailed in section 4.6 and 4.9.

4.4 Foundation

4.4.1 Rigid baseplates - overviewThe function of a baseplate is to provide a rigidfoundation under a pump and its driver thatmaintains alignment between the two.

Baseplates intended for grouted installation aredesigned to use the grout as a stiffening member.

Regardless of the type of baseplate used, it mustprovide three functions to ensure a reliableinstallation.a) The baseplate must provide sufficient rigidity to

assure the assembly can be transported andinstalled, given reasonable care in handling,without damage. It must also be rigid enoughwhen properly installed to resist operating loads.

b) The baseplate must provide a reasonably flatmounting surface for the pump and driver.Uneven surfaces will result in a soft-footcondition that may make alignment difficult orimpossible. Flowserve’s experience indicatesthat a baseplate that has a top surface flatnessof ±1.6 mm (±1/16 in.) across the diagonalcorners of the baseplate provides such amounting surface. Therefore, this is thetolerance to which we supply our standardbaseplate.

c) The baseplate must be designed to allow theuser to final field align the pump and driver towithin their own particular standards and tocompensate for any pump or driver movement

that occurred during handling. Normal industrypractice is to achieve final alignment by movingthe motor to match the pump. Flowserve’spractice is to confirm in our shop that the pumpassembly can be accurately aligned. Beforeshipment, the factory verifies that there isenough horizontal movement capability at themotor to obtain a “perfect” final alignment whenthe installer puts the baseplate assembly into itsoriginal, top leveled, unstressed condition.

4.4.2 Foundation D-814Flowserve recommends mounting D-814 pumps onpermanent foundations to prevent excessive strainsfrom piping connections and couplingmisalignment. Figure 4-1 shows a typicalinstallation.

Ideally pumps should be installed in a horozontalposition using steel baseplates on a permanentmasonry or structural steel foundation of sufficientmass to absorb all normal vibrations. Foundationbolts should be located or embedded in theconcrete by layout or template in relation to thesuction and discharge piping. If concrete is used,foundation bolts of the specified size may beenclosed in a pipe sleeve two or three diameterslarger than the bolts to compensate for minorvibration in lineup.

Channel steel bases are bolted in place. Drain rimsteel bases may be grouted if desired.Accessory steel baseplates furnished with thesepumps and motors 10 hp and under may be boltedto machine or equipment structures, either rigidlyor, if flexible piping is used, with properly designedvibration isolators.

Small units (10 hp and under) may be operated intempory installations without permanent foundationattachments if mounted on standard channel steelor drain rim steel baseplates under the followingconditions.

a) Use flexible piping connections such as hosewhich will not impose heavy pipe strains onpump casing but will not rupture or leak if unitshifts slightly due to vibration or external forces.

b) Connect motor with safe durable electricalconnections which will not be affected by slightshifting of the unit.

c) Conditions of coupling misalignment mayshorten life of motor and pump bearings.

FIGURE 4-1 Typical Installation

4.4.3 Foundation D-824The main purpose of the mounting for theMonobloc pump is to prevent any shifting whichcould result in the pump weight being supported bythe connection piping. If this happens, internaldamage to pump parts could occur. If flexible pipingor hose is used, the mounting need only supportthe weight of the pump and any vibrations thatmight occur. Monobloc pumps are normallymounted horizontally. However, they may bemounted vertically or in other positions. If the liquidend is above motor, any leakage from the pumpmay enter and damage the motor bearings.Monobloc pumps should be fastened to theirfoundations by using four of the mounting boltholes in the motor feet. Do not depend upon pipingto hold the pump in place even with the smallestunits. Bolt pumps above 15 hp to masonry orstructural steel foundations. Smaller units may bebolted to machine or equipment structures eitherrigidly or, flexible piping is used, with properlydesigned vibration isolators. Units with largecasings and small motors require a builtupmounting under the motor feet. On some largeunits, an auxiliary foot is provided under the casing.The feet must match mounting surfaces exactly orit will be necessary to shim. Tighten the motormounting bolts after the piping connections aresecurely attached to the pump.

4.5 Grouting

This section applies only to drip rim offormed steel baseplates with grout holes.

a) The pump foundation should be located asclose to the source of the fluid to be pumpedas practical. There should be adequate spacefor workers to install, operate and maintain thepump. The foundation should be sufficient toabsorb any vibration and should provide arigid support for the pump and motor.Recommended mass of a concrete foundationshould be three times that of the pump, motorand base. Refer to Figure 4-2. Note thatfoundation bolts are imbedded in the concreteinside a sleeve to allow some movement of thebolt.

FIGURE 4-2

b) Level the pump baseplate assembly. If thebaseplate has machined coplanar mountingsurfaces, these machined surfaces are to bereferenced when leveling the baseplate. Thismay require that the pump and motor beremoved from the baseplate in order toreference the machined faces. If thebaseplate is without machined coplanarmounting surfaces, the pump and motor are tobe left on the baseplate. The proper surfacesto reference when leveling the pump baseplateassembly are the pump suction and dischargeflanges. DO NOT stress the baseplate. Donot bolt the suction or discharge flanges of thepump to the piping until the baseplatefoundation is completely installed. If equipped,use leveling jackscrews to level the baseplate.If jackscrews are not provided, shims orwedges should be used (see Figure 4-2).Check for levelness in both the longitudinaland lateral directions. Shims should be placedat all base anchor bolt locations, and in themiddle edge of the base if the base is morethan 1.5 m (5 ft) long. Do not rely on thebottom of the baseplate to be flat. Standardbaseplate bottoms are not machined, and it isnot likely that the field mounting surface is flat.

c) After leveling the baseplate, tighten the anchorbolts. If shims were used, make sure that thebaseplate was shimmed near each anchor boltbefore tightening. Failure to do this may resultin a twist of the baseplate, which could make itimpossible to obtain final alignment. Checkthe level of the baseplate to make sure thattightening the anchor bolts did not disturb thelevel of the baseplate. If the anchor bolts didchange the level, adjust the jackscrews orshims as needed to level the baseplate.Continue adjusting the jackscrews or shimsand tightening the anchor bolts until thebaseplate is level.

d) Check initial alignment. Pumps are given apreliminary alignment at the factory. Thispreliminary alignment is done in a way that

ensures that, if the installer duplicates thefactory conditions, there will be sufficientclearance between the motor hold down boltsand motor foot holes to move the motor intofinal alignment. If the pump and motor wereproperly reinstalled to the baseplate or if theywere not removed from the baseplate andthere has been no transit damage, and also ifthe above steps where done properly, thepump and driver should be within 0.38 mm(0.015 in.) FIM (Full Indicator Movement)parallel, and 0.0025 mm/mm (0.0025 in./in.)FIM angular. If this is not the case, first checkto see if the driver mounting fasteners arecentered in the driver feet holes. If not, re-center the fasteners and perform a preliminaryalignment to the above tolerances byshimming under the motor for verticalalignment, and by moving the motor forhorizontal alignment.

e) Grout the baseplate. A non-shrinking groutshould be used. Make sure that the grout fillsthe area under the baseplate. After the grouthas cured, check for voids and repair them.Jackscrews, shims and wedges should beremoved from under the baseplate at this time.If they were to be left in place, they could rust,swell, and cause distortion in the baseplate.

f) Run piping to the suction and discharge of thepump. There should be no piping loadstransmitted to the pump after connection ismade. Recheck the alignment to verify thatthere are no significant loads.

4.6 Initial alignmentMounting and alignmentPumps operate most reliably when carefully alignedon permanent rigid foundations. Strains which willcause wear of internal parts of the pump andexcessive noise and vibration are eliminated thisway.

Pump-driver combinations are aligned at thefactory but must be rechecked for couplingalignment because they may be sprung in shipmentor distorted by tightening of foundation bolts.

The best procedure to follow is to remove thecoupling guard and check coupling alignmentbefore tightening any foundation bolts.

If the pump is mounted on a permanent foundation,tighten the bolts now and recheck couplingalignment. Also turn the shaft by hand to assurethat it turns freely.


of 36

®

If unit is to be grouted do it now. After the grout hasbeen poured and allowed to set for 48 hours tightenfoundation bolts evenly and securely. Recheckcoupling alignment. Replace coupling guard.

Pumps on hot survice should have final couplingalignment made with the unit at its operatingtemperature.

4.6.1 Factory alignment procedure.The purpose of factory alignment is to ensure thatthe user will have full utilization of the clearance inthe motor holes for final job-site alignment. Toachieve this, the factory alignment procedurespecifies that the pump be aligned in the horizontalplane to the motor, with the motor foot boltscentered in the motor holes. This procedureensures that there is sufficient clearance in themotor holes for the customer to field align the motorto the pump, to zero tolerance. This philosophyrequires that the customer be able to place thebase in the same condition as the factory. Thusthe factory alignment will be done with the basesitting in an unrestrained condition on a flat andlevel surface. This standard also emphasizes theneed to ensure the shaft spacing is adequate toaccept the specified coupling spacer.

The factory alignment procedure is summarizedbelow:

a) The baseplate is placed on a flat and levelworkbench in a free and unstressed position.

b) The baseplate is leveled as necessary.Leveling is accomplished by placing shimsunder the rails of the base at the appropriateanchor bolt hole locations. Levelness ischecked in both the longitudinal and lateraldirections.

c) The motor and appropriate motor mountinghardware is placed on the baseplate and themotor is checked for any planar soft-footcondition. If any is present it is eliminated byshimming

d) The motor feet holes are centered on themotor mounting fasteners.

e) The motor is fastened in place by tighteningthe nuts on two diagonal motor mountingstuds.

f) The pump is put onto the baseplate andleveled. The foot piece under the bearinghousing is adjustable. It is used to level thepump, if necessary.

g) The spacer coupling gap is verified.h) The parallel and angular vertical alignment is

made by shimming under the motor.

i) The motor feet holes are again centered onthe motor mounting studs using the centeringnut. At this point the centering nut is removedand replaced with a standard nut. This givesmaximum potential mobility for the motor to behorizontally moved during final, fieldalignment. All four motor feet are tighteneddown.

j) The pump and motor shafts are then alignedhorizontally, both parallel and angular, bymoving the pump to the fixed motor. Thepump feet are tightened down.

k) Both horizontal and vertical alignment is againfinal checked as is the coupling spacer gap.

See section 4.9 for Final shaft alignment

4.7 Piping

The protective covers fitted to boththe suction and discharge of the casing must beremoved prior to connecting the pump to any pipes.

Isolation valves on suction and discharge lines arerecommended to facilitate future inspection andrepairs.

4.7.1 Suction and discharge pipingAll piping must be independently supported,accurately aligned and preferably connected to thepump by a short length of flexible piping. Thepump should not have to support the weight of thepipe or compensate for misalignment. It should bepossible to install suction and discharge boltsthrough mating flanges without pulling or pryingeither of the flanges. All piping must be tight.Pumps may air-bind if air is allowed to leak into thepiping. If the pump flange(s) have tapped holes,select flange fasteners with thread engagement atleast equal to the fastener diameter but that do notbottom out in the tapped holes before the joint istight.

4.7.2 Suction pipingTo avoid NPSH and suction problems, suctionpiping must be at least as large as the pumpsuction connection. Never use pipe or fittings onthe suction that are smaller in diameter than thepump suction size.

Figure 4-3 illustrates the ideal piping configurationwith a minimum of 10 pipe diameters between thesource and the pump suction. In most cases,horizontal reducers should be eccentric andmounted with the flat side up as shown in Figure 4-4 with a maximum of one pipe size reduction.


of 36

®

Never mount eccentric reducers with the flat sidedown. Horizontally mounted concentric reducersshould not be used if there is any possibility ofentrained air in the process fluid. Verticallymounted concentric reducers are acceptable. Inapplications where the fluid is completelydeaerated and free of any vapor or suspendedsolids, concentric reducers are preferable toeccentric reducers

Avoid the use of throttling valves and strainers inthe suction line. Start up strainers must beremoved shortly before start up. When the pump isinstalled below the source of supply, a valve shouldbe installed in the suction line to isolate the pumpand permit pump inspection and maintenance.Never place a valve directly on the suction nozzleof the pump.

Refer to the Centrifugal Pump Section of theHydraulic Institute Standards for additionalrecommendations on suction piping.Refer to section 3.4 for performance and operatinglimits.

4.7.3 Net positive suction headThe NPSH required varies with every size of pumpand for any given pump is varies with the capacity.The NPSH required by your unit can be obtainedfrom the performance curves available from yourFlowserve Pump Division representative.

To determine the NPSH available in your systemrefer to Figure 4-1 and the following equation.

Avaliable (P-PV)2.31 NPSH = ? Z + Sp. Gr. Hf -He

Where Z = Static head in feetP = Pressure on surface of liquid in psiaPV = Vapor pressure of liquid at pumpingtemperature in psiaHf = Suction line friction losses in feetHe = Entrance Loss from tank to pipe in feet

For boiling liquids P equals PV and thisitem can be omitted from the equation.

If the available NPSH is not equal to or greater thanthat required by the pump, it must be increased.This is usually done by increasing the static head,Z.

4.7.4 Discharge pipingInstall a valve in the discharge line. This valve isrequired for regulating flow and/or to isolate thepump for inspection and maintenance.

When fluid velocity in the pipe ishigh, for example, 3 m/s (10 ft/sec) or higher, arapidly closing discharge valve can cause adamaging pressure surge. A dampeningarrangement should be provided in the piping.

4.7.5 Pump and shaft alignment checkAfter connecting the piping, rotate the pump driveshaft clockwise (view from motor end) by handseveral complete revolutions to be sure there is nobinding and that all parts are free. Recheck shaftalignment (see section 4.6). If piping caused unit tobe out of alignment, correct piping to relieve strainon the pump.

4.7.6 Mechanical sealIt is Flowserve’s standard practice to install themechanical seal in the pump prior to shipment.Specific order requirements may specify that theseal be shipped separately, or none be supplied. Itis the pump installer’s responsibility to determine ifa seal was installed. If a seal was supplied but notinstalled, the seal and installation instructions willbe shipped with the pump.

FIGURE 4-3 and FIGURE 4-4


of 36

®

Failure to ensure that a seal isinstalled may result in serious leakage of thepumped fluid.

Seal and any seal support system (if used) must beinstalled and operated as specified by the sealmanufacturer.

The cover may have ports that have beentemporarily plugged at the factory to keep outforeign matter. It is the installer’s responsibility todetermine if these plugs should be removed andexternal piping connected.

4.8 Electrical connections

4.8.1 Electrical connections must bemade by a qualified Electrician in accordance withrelevant local national and international regulations.

4.8.2 The motor must be wired up inaccordance with the motor manufacturer'sinstructions (normally supplied within the terminalbox) including any temperature, earth leakage,current and other protective devices as appropriate.The identification nameplate should be checked toensure the power supply is appropriate.

4.8.3 See section 5.2, Direction ofrotation before connecting the motor to theelectrical supply.

4.9 Final shaft alignment check forhorizontal pumpsa) Level baseplate if appropriate.b) Mount and level pump if appropriate. Level

the pump by putting a level on the dischargeflange. If not level, adjust the pump bracketbearing frame as follows:

c) Check initial alignment. If pump and driverhave been remounted or the specificationsgiven below are not met, perform an initialalignment as described in Section 4.6. Thisensures there will be sufficient clearancebetween the motor hold down bolts and motorfoot holes to move the motor into finalalignment. The pump and driver should bewithin 0.38 mm (0.015 in.) FIM (Full IndicatorMovement) parallel, and 0.0025 mm/mm(0.0025 in./in.) FIM angular.

d) Run piping to the suction and discharge to thepump. There should be no piping loadstransmitted to the pump after connection is

made. Recheck the alignment to verify thatthere are no significant changes.

e) Perform final alignment. Check for soft-footunder the driver. An indicator placed on thecoupling, reading in the vertical direction,should not indicate more than 0.05 mm (0.002in.) movement when any driver fastener isloosened. Align the driver first in the verticaldirection by shimming underneath its feet.When satisfactory alignment is obtained thenumber of shims in the pack should beminimized. It is recommended that no morethan five shims be used under any foot. Finalhorizontal alignment is made by moving thedriver. Maximum pump reliability is obtainedby having near perfect alignment. Flowserverecommends no more than 0.05 mm (0.002in.) parallel, and 0.0005 mm/mm (0.0005in./in.) angular misalignment (see Section6.8.7.2).

f) Operate the pump for at least an hour or until itreaches final operating temperature. Shut thepump down and recheck alignment while thepump is hot. Piping thermal expansion maychange the alignment. Realign pump asnecessary.

5 COMMISSIONING, STARTUP,OPERATION AND SHUTDOWN

5.1 Pre-commission procedure

Pre start-up checksPrior to starting the pump preform the followingchecks. All checks are described in the MaintenanceSection of this manual.? Pump and motor properly secured to the

baseplate? All fasteners tightened to the correct torque? Coupling guard in place and not rubbing? Rotation check, see section 5.2

This is absolutely essential? Shaft seal properly installed (if field installed)? Seal support system operational (if used)? Pump instrumentation is operational (if used)? Pump is primed? Pump shaft rotates freely by hand

Preliminary to startingRead this instruction book thoroughly before startingthe unit. Make sure the following items are checkedbefore starting:

? Alignment? Lubricate the driver (if required)? Check the direction of rotation of the driver? Lubricate the coupling (if required)? Fill the pump with liquid. If a priming device is

used, turn it on before the pump is started

5.2 Direction of rotation

5.2.1 Rotation checkCheck the rotation of the motor before connecting theshaft coupling. A direction arrow is cast on thecasing. Make sure the motor rotates in the samedirection.

5.2.2 Coupling installationRemove all protective material from the coupling andshaft. Install the coupling as advised by the couplingmanufacturer. Pumps are normally shipped withoutthe spacer installed, but with the hubs installed.

5.3 GuardingPower must never be applied to the driver with thecoupling guard removed.

5.4 Priming and auxiliary supplies

The D-800 is a centrifugal pump and is unable tomove liquid unless primed. A pump is said to be“primed” when the casing and the suction piping arecompletely filled with liquid. When a condition existswhere the suction pressure may drop below thepump’s capability, a low-pressure control deviceshould be added to shut the pump down when thepressure drops below a predetermined minimum.

PrimingBefore starting any centrifugal pump it is absolutelynecessary that both the casing and suction pipe becompletely filled with liquid. This priming can beaccomplished by any of the following methods.

a) When the liquid supply level is above the centerline of the pump, it is primed by opening thesuction and discharge valves. The inflowing liquidwill displace the air and fill the suction line, pumpcasing, and discharge line up to the level ofsupply.

b) Where the pump is operating with suction lift andthe suction line is equipped with a foot valve, thesystem is filled with liquid by filling through thedischarge piping.

c) When the pumps operating on a suction lift wherefoot valves will not operate properly, a primingchamber may be used.

d) Instead of the preceding methods of filling thepump, one of a number of types of air removalapparatus may be used, depending upon thefacilities available. This apparatus is requiredwhen the pump operates under a suction lift andthere is no foot valve in the suction pipe. Theconnections are made in the top if the pipe at thepump suction opening. To prime, shut thedischarge valve and do not start the driver untilthe pump and piping are full or water.

5.5 Starting the pump

5.5.1 Open the suction valve to full open position.Always leave the suction valve open while the pumpis operating. Any throttling or adjusting of flow mustbe done through the discharge valve. Partiallyclosing the suction valve can create serious NPSHand pump performance problems.

Operating a pump with both thesuction and discharge valves closed could cause anexplosion.

5.5.2 Ensure the pump is primed. (See section 5.4)

5.5.3 Start the driver (typically, an electric motor).

5.5.4 Slowly open the discharge valve until thedesired flow is reached.

It is important that the discharge valvebe opened within a short interval after starting thedriver. Failure to do this could cause a dangerousbuild up of heat, and possibly an explosion.

StartingThe procedure for starting the unit will vary somewhatwith each installation but the following steps willgenerally apply:

a) Make certain that suction and discharge valvesare open.

b) Start the driver.c) Check to see that the pump is delivering liquid.d) When in service for about one half hour check for

quiet operation and temperature of bearings.After the pump reaches operating temperatureshut it down. Then check the alignment andcheck for binding.

5.6 Running or operation

5.6.1 Minimum continuous flowMinimum continuous stable flow is the lowest flow atwhich the pump can operate. The size of the pump,the energy absorbed, and the liquid pumped aresome of the considerations in determining theminimum continuous flow (MCF).The minimum continuous flow (capacity) isestablished as a percentage of the best efficiencypoint (BEP).

5.6.2 Minimum thermal flowPumps also have a minimum thermal flow. This isdefined as the minimum flow that will not cause anexcessive temperature rise. Minimum thermal flow isapplication dependent.

Do not operate the pump belowminimum thermal flow, as this could cause anexcessive temperature rise.

Avoid running a centrifugal pump at drasticallyreduced capacities or with discharge valve closed forextended periods of time. This can cause severetemperature rise and the liquid in the pump mayreach its boiling point. If this occurs, the mechanicalseal will be exposed to vapor, with no lubrication, andmay score or seize to the stationary parts. Continuedrunning under these conditions when the suctionvalve is also closed can create an explosive conditiondue to the confined vapor at high pressure andtemperature.

Thermostats may be used to safeguard against overheating by shutting down the pump at apredetermined temperature.

Safeguards should also be taken against possibleoperation with a closed discharge valve, such asinstalling a bypass back to the suction source. Thesize of the bypass line and the required bypass flowrate is a function of the input horsepower and theallowable temperature rise.

5.6.3 Reduced headNote that when discharge head drops, the pump’sflow rate usually increases rapidly. Check motor fortemperature rise as this may cause overload. Ifoverloading occurs, throttle the discharge.

5.6.4 Surging conditionA rapidly closing discharge valve can cause adamaging pressure surge. A dampeningarrangement should be provided in the piping.

5.6.5 Operation in sub-freezing conditionsWhen using the pump in sub-freezing conditionswhere the pump is periodically idle, the pump shouldbe properly drained or protected with thermal deviceswhich will keep the liquid in the pump from freezing.

5.7 Stopping and shutdownThe procedure for stopping may vary with eachinstallation the following steps will generally apply

a) Close the discharge valve.b) Shut down the driver.c) Close the suction valve.

5.8 Hydraulic, mechanical and electricalduty

5.8.1 Net positive suction head (NPSH)Net positive suction head - available (NPSHA) is themeasure of the energy in a liquid above the vaporpressure. It is used to determine the likelihood that afluid will vaporize in the pump. It is critical because acentrifugal pump is designed to pump a liquid.Vaporization in a pump will result in damage to thepump, deterioration of the Total differential head(TDH) and possibly a stop of pumping.

Net positive suction head - required (NPSHR) is thedecrease of fluid energy between the inlet of thepump and the point of lowest pressure in the pump.The decrease occurs because of friction losses andfluid accelerations in the inlet region of the pump,particularly accelerations as fluid enters the impellervanes. The value for NPSHR for the specific pumppurchased is given on the pump performance curve.

For a pump to operate properly the NPSHA must begreater than the NPSHR. Good practice dictates thatthis margin should be at least 1.5 m (5 ft) or 20%,whichever is greater.

Ensuring that NPSHA is larger thanNPSHR by the suggested margin will enhance pumpperformance and reliability. It will also reduce the riskof cavitation, which can severely damage the pump.

5.8.2 Specific gravity (SG)Pump capacity and total head are constant with SG.However pressure displayed on a pressure gauge isdirectly proportional to SG. Power absorbed is alsodirectly proportional to SG. Therefore, check that anychange in SG will not overload the pump driver oroverpressurize the pump.

5.8.3 ViscosityFor a given flow rate the total head reduces withincreased viscosity and increases with reducedviscosity. For a given flow rate the power absorbedincreases with the increased viscosity, and reduceswith reduced viscosity.

5.8.4 Pump speedChanging the pump speed affects flow, total head,power absorbed, NPSHr, noise and vibration levels.Flow varies in direct proportion to pump speed. Headvaries as speed ratio squared. Power varies asspeed ratio cubed. If increasing speed ensure themaximum working pressure is not exceeded, driver isnot overloaded, NPSHa>NPSHr, noise and vibrationare within local requirements and regulations.

6 MAINTENANCE

It is the plant operator's responsibility to ensurethat all maintenance, inspection and assembly workis carried out by authorized and qualified personnelwho have adequately familiarized themselves withthe subject matter by studying this manual in detail.(See also section 1.6.2.)

Any work on the machine must be performed when itis at a standstill. It is imperative that the procedurefor shutting down the machine is followed, asdescribed in section 5.7.

On completion of work all guards and safety devicesmust be re-installed and made operative again.

Before restarting the machine, the relevantinstructions listed in section 5, Commissioning, startup, operation and shut down must be observed.

Oil and grease leaks may make the groundslippery. Machine maintenance must alwaysbegin and finish by cleaning the ground and theexterior of the machine.

If platforms, stairs and guard rails are required formaintenance, they must be placed for easy access toareas where maintenance and inspection are to becarried out. The positioning of these accessoriesmust not limit access or hinder the lifting of the part tobe serviced.

When air or compressed inert gas is used in themaintenance process, the operator and anyone in thevicinity must be careful and have the appropriateprotection.

Do not spray air or compressed inert gas on skin.

Do not direct an air or gas jet towards other people.

Never use air or compressed inert gas to cleanclothes.

Before working on the pump, take measures toprevent the pump from being accidentally started.Place a warning sign on the starting device:"Machine under repair: do not start".

With electric drive equipment, lock the main switchopen and withdraw any fuses. Put a warning sign onthe fuse box or main switch:"Machine under repair: do not connect".

Never clean equipment with flammable solvents orcarbon tetrachloride. Protect yourself against toxicfumes when using cleaning agents.

Refer to the parts list shown in section 8 for itemnumber references used throughout this section.

6.1 Maintenance scheduleIt is recommended that a maintenance plan andschedule be implemented, in accordance with theseUser Instructions, to include the following:a) Any auxiliary systems installed must be

monitored, if necessary, to ensure they functioncorrectly.

b) Check for any leaks from gaskets and seals. Thecorrect functioning of the shaft seal must bechecked regularly.

c) Check that the duty condition is in the safeoperating range for the pump.

d) Check vibration, noise level and surfacetemperature at the bearings to confirmsatisfactory operation.

e) Check dirt and dust is removed from areas aroundclose clearances, bearing housings and motors.

Check coupling alignment and re-align if necessary

6.1.1 Preventive maintenanceThe following sections of this manual give instructionson how to perform a complete maintenance overhaul.However, it is also important to periodically repeat thePre start-up checks listed in section 5.1. Thesechecks will help extend pump life as well as thelength of time between major overhauls.

6.1.2 Need for maintenance recordsA procedure for keeping accurate maintenancerecords is a critical part of any program to improvepump reliability. There are many variables that cancontribute to pump failures. Often long term andrepetitive problems can only be solved by analyzingthese variables through pump maintenance records.

6.1.3 CleanlinessOne of the major causes of pump failure is thepresence of contaminants in the bearing housing.This contamination can be in the form of moisture,dust, dirt and other solid particles such as metalchips. Contamination can also be harmful to themechanical seal (especially the seal faces) as well asother parts of the pump.

6.1.4 Mechanical sealA pump equipped with a mechanical seal must not berun until the pump casing is full of liquid. Running apump dry will damage the mechanical seal.For further information on assembly of themechanical seal refer to the following subsections.

6.1.5 Bearing lubricationMotors may have grease lubricated bearings whichmay require periodic replacement of grease. Refer tothe instructions on/or supplied with motor.

The D-814 pump bearing frame is equipped withsealed for life bearings which do not requireadditional lubrication.

6.2 Spare partsThe decision on what spare parts to stock variesgreatly depending on many factors such as thecriticality of the application, the time required to buyand receive new spares, the erosive/corrosive natureof the application, and the cost of the spare part.Section 8 identifies all of the components that makeup each pump addressed in this manual.

6.2.1 Order of spare partsFlowserve keeps records of all pumps that have beensupplied. Spare parts can be ordered from your localFlowserve Distributor or Representative. Whenordering spare parts the following information shouldbe supplied:Model D-814 or D-824a) Serial numberb) Size typec) Part name – see section 8d) Part item number – see section 8e) Material of construction (if known)f) Number of parts requiredg) Impeller diameter

The pump size and serial number can be found onthe name plate. See section 3.2.

6.2.2 Returning partsAll materials returned to the factory must have aReturn Material Authorization. Consult the nearestFlowserve Pump Division representative for shippinginstructions and a Return Material Order Number.

Unnecessary delays are avoided when parts orequipment are returned to the factory using thecorrect procedure.

a) Contact your nearest Flowserve Pump Divisionreprestative, listing the material to be returnedand the reasons for returning it. Make sure yougive the description of the part and it’s itemnumber from section 8.

b) On receipt of the Return Material Order Number,mark or tag the material to be returned with thisorder number. In cases where more than onepart or box is returned, print or stencil your nameand the Return Material Order Number on eachpart or box. This will facilitate quick identification.

c) Articles being returned should be carefullypacked to prevent damage from handeling orfrom the exposure to weather. Give the methodand date of shipment. This will notify the factorythat the material is enroute.

6.5 Disassembly procedurea) Remove bolts which hold casing to cover.b) Separate casing from cover (a pry bar or large

screw driver can be used if needed).c) Remove old casing gasket.d) Remove the impeller fastening hardware.e) Remove the impeller and key from the shaft.f) The sleeve and mechanical seal rotating

assembly can be removed from the shaft as aunit.

g) Remove the bolts which hold the cover to themotor or frame.

h) Remove the cover from the motor or frame.i) Working from the backside of the cover, push the

seal seat out using a plastic drift or other suitabledevice.

j) Remove the rotating assembly portion of themechanical seal assembly from the sleeve.

k) Casing wear ring, if equipped, can be removedthrough the suction opening by the same methodas for the cover ring, using a specially sharpeneddrift pin or by drilling holes in the ring to split it.

Do not strike the shaft, impeller orsleeve with a hammer. This will damage the ballbearings and shaft.

6.5.1 Disassembly of framea) If there is any reason to suspect a bent shaft or a

misalignment problem, the shaft should bechecked for runout with a dial indicator beforedisassembling the bearing frame. Maximumrunout at mechanical seal is 0.002 in.

b) To disassemble the bearing frame, remove the 4cap screws that hold the bearing cover [3260] tothe bearing housing [3200].

c) Remove the shaft [2100] and bearings [3041 and3043] by pressing on the impeller end of theshaft. Protect the threaded end of the shaftduring this operation. In this process the deflector[2540] will be pushed off the shaft.

d) The bearings may be removed from the shaft byconventional pressing or pulling methods oncethe retaining ring [2530] is removed.

6.6 Examination and repair of parts

With pump liquid end dissembled, clean all parts andcheck for worn and damaged areas. It is seldomeconomical on the D-800 pumps to repair damagedor worn parts. Therefore, when a part is unusable, itshould be replaced.

6.6.1 CasingClean and inspect gasket surfaces for damagedareas that would cause leaks. Check casing wearring surfaces for excessive wear. Figure 6-2 givesstandard casing wear ring clearances for cover andcasing sides of the impeller.

6.6.2 ImpellerCheck casing wear ring surfaces for excess wear,impeller vanes, and gasket surfaces of impeller hubfor damage. If excessively worn or eroded, theimpeller must be replaced.

6.6.2.1 Impeller balancingShaft whip is deflection where the centerline of theimpeller is moving around the true axis of the pump.It is not caused by hydraulic force but rather by animbalance with the rotating element. Shaft whip isvery hard on the mechanical seal because the facesmust flex with each revolution in order to maintaincontact. To minimize shaft whip it is imperative thatthe impeller is balanced. All impellers manufacturedby Flowserve are balanced after they are trimmed. Iffor any reason, a customer trims an impeller, it mustbe re-balanced.

6.6.3 AlignmentMisalignment of the pump and motor shafts cancause the following problems:? Failure of the mechanical seal? Failure of the motor and/or pump bearings? Failure of the coupling? Excessive vibration/noise

Pipe Strain Movement

The schematics below show the technique for atypical rim and face alignment using a dial indicator.It is important that this alignment be done after theflanges are loaded, and at typical operatingtemperatures.

Many companies today are using laser alignmentwhich is a more sophisticated and accuratetechnique. With this method a laser and sensormeasure misalignment. This is fed to a graphicdisplay that shows the required adjustment for eachof the motor feet.

6.6.3.2 Vibration analysisVibration analysis is a type of condition monitoringwhere a pump’s vibration “signature” is monitored ona regular, periodic basis. A problem can be noticedbefore it becomes serious by using this tool. This canalso help find the root cause of the problem andpossible solutions.

On a centrifugal pump causes can include thefollowing: unbalance, misalignment, defectivebearings, resonance, hydraulic forces, cavitation andrecirculation.

Flowserve urges customers to work with anequipment supplier or consultant to establish an on-going vibration analysis program.

6.6.4 CoverClean and inspect gasket surfaces. Clean themechanical seal cavity. Check cover ring for wearand excess clearance. See Figure 6-2. Cover ringsmay be driven out by use of a hammer and drift pin.Removing cast iron casing rings requires specialprocedures beyond the scope of this instruction book.

6.6.5 SleeveCheck for any damage to gasket surface on impellerend, O-ring groove on driver end, or outside diameterwhere rubber bellows of mechanical seal contacts.

6.6.6 Mechanical sealIt is normal pratice to replace the mechanical seealwhen rebuilding a pump.

6.6.7 Motor shaftCheck the shaft for any bent condition by installingthe sleeve, clamping a dial indicator to the motorframe face and reading a runout at the center of thesleeve while turning the shaft by hand. Maximumallowable runout is 0.002 inches for properperformance of mechanical seal. A runout readinggreater than this maximum indicates the motorrequires repairs beyond the scope of this instructionbook.

6.7 Assembly of pump and sealThe D-814 and D-824 pumps are easy to puttogether. Tasks requiring the most care are theinstallation of the mechanical seal and bearings.

a) Study section 8, Parts List and Drawings, andbecome familiar with the name of each part of theassembled pump.

b) Make sure all the parts are clean and ready forassembly. This means no dirt or pieces of oldgaskets in the joints between the motor, coverand casing. Make sure the parts around themechanical seal are clean. Dirt and misalignmentwill ruin the mechanical seal.

c) Install the sleeve O-ring in place against the shaftshoulder. Sharp edges of the keyway can cut theO-ring.

d) Press in the cover ring, beveled edge first, usinga pressure tool that will hold the ring square withthe cover bore. A little lubricant will easepressing. Be careful not to gouge or distort thering.

e) Push the stationary element squarely into thecover. The stationary element O-ring can belubricated to ease installation into the cover.Don’t install the cover on the motor or bearingframe yet. Clean the face of the stationaryelement.

f) Check the sleeve fit on the motor shaft. It shouldslide easily into place. If it doesn’t, find out why.Do not try to drive the sleeve on to the shaft witha hammer. Check to make sure there are noscore marks or scratches on the sleeve.

g) Install the cover and tighten the bolts that hold itto the motor or bearing frame. Make sure thenameplate is properly positioned.

h) Slide the sleeve on the shaft so that it covers thesleeve O-ring and butts against the shoulder.

i) Lubricate the inside of the rotating elementbellows and install on the sleeve by hand. Atwisting motion may be needed to make it ridesmoothly over the shoulders on the sleeve. Pushit by hand until it contacts the stationary element.Install the spring and spring holder.

j) Install the retaining ring using one hand to holdthe retaining ring pliers and the other hand tocompress the spring. When the spring pressureis released, the spring will push the sleeveoutward, temporarily exposing the sleeve O-ring.

k) Install the key, first twisting the sleeve on theshaft untill both keyways line up.

l) Install the sleeve gasket.m) Place the impeller on the shaft, engaging the key.n) Put the impeller screw gasket, impeller washer

and impeller washer gasket together on theimpeller screw as a subassembly.

o) Install the impeller screw subassembly. With onehand, push the impeller back against themechanical seal spring and with the other handturn the impeller screw in hand tight.

p) Tighten the impeller screw 15 lbf.ft torque for 3/8in. thread (motor frame sizes 143-215), 20 lbf.fttorque for 1/2 in. thread (frame 254 up), and 30lbf.ft torque for 5/8 in. thread (15 in. pumps).

q) Install the casing gasket in the casing.r) Install the casing and tighten all bolts. Tighten the

bolts 15 lbf.ft torque on 4, 5 and 6 in. pumps, 30lbf.ft torque on 8, 9, 10, 11, 12 and 13 in. pumpsand 60 lbf.ft torque on 15 in. pumps.

s) Turn the motor shaft and check for and bindingor rubs caused by such things as damaged ormisaligned parts. Any such conditions must becorrected before the pump is run.

The pump is now ready for installation.

6.7.1 Assembly of frameUse the following procedure to assemble the bearingframe.

a) Press bearings on shaft. Note that the inboardbearing [4041] can face either way. However, theoutboard bearing [4043] must face in the properdirection, as illustrated in section 8.5.

b) Install the shaft and bearing subassembly in thebearing housing [3200] by inserting from couplingend and pushing through until the retaining ringcontacts the back face of the housing.

c) Install bearing cover [3260] and bolts.d) Install deflector [2540].e) Install the pump bracket on the frame using its

hardware.

7 FAULTS; CAUSES AND REMEDIES

TroubleshootingThe following is a guide to troubleshooting problems with Flowserve D-800 pumps. Common problems areanalyzed and solutions offered. Obviously, it is impossible to cover every possible scenario. If a problem existsthat is not covered by one of the examples, then refer to one of the books listed in the Sources of additionalinformation section or contact a Flowserve Sales Engineer or Distributor/Representative for assistance.

FAULT SYMPTOMPump not reaching design flow rate

?? Pump not reaching design head (TDH)

?? No discharge or flow with pump running

?? Pump operates for short period, then loses prime

?? Excessive noise from wet end

?? Excessive noise from power end

??

??

??

??

?? PROBABLE CAUSES POSSIBLE REMEDIES

? ? ? ? Insufficient NPSH. (Noise may not bepresent.)

Recalculate NPSH available. It must be greater than theNPSH required by pump at desired flow. If not, redesignsuction piping, holding number of elbows and number ofplanes to a minimum to avoid adverse flow rotation as itapproaches the impeller.

? ? ? System head greater than anticipated. Reduce system head by increasing pipe size and/orreducing number of fittings. Increase impeller diameter.(NOTE: Increasing impeller diameter may require use ofa larger motor.)

? ? ? Entrained air. Air leak from atmosphere onsuction side.

1. Check suction line gaskets and threads for tightness.2. If vortex formation is observed in suction tank, installvortex breaker.3. Check for minimum submergence

? ? Entrained gas from process. Process generated gases may require larger pumps.

? ? Speed too low. Check motor speed against design speed.

? ? ? Direction of rotation wrong. After confirming wrong rotation, reverse any two of threeleads on a three phase motor. The pump should bedisassembled and inspected before it is restarted.

? ? Impeller too small. Replace with proper diameter impeller. (NOTE:Increasing impeller diameter may require use of a largermotor.)

? ? Wet end parts (casing cover, impeller) worn,corroded or missing.

Replace part or parts.

? ? Not properly primed. Repeat priming operation, recheck instructions. If pumphas run dry, disassemble and inspect the pump beforeoperation.

? Impeller rubbing. 1. Check and reset impeller clearance.2. Check outboard bearing assembly for axial end play.

? ? Damaged pump shaft, impeller. Replace damaged parts.

? Abnormal fluid rotation due to complex suctionpiping.

Redesign suction piping, holding the number of elbowsand planes to a minimum to avoid adverse fluid rotationas it approaches the impeller.

FAULT SYMPTOMPump not reaching design flow rate

?? Pump not reaching design head (TDH)

?? No discharge or flow with pump running

?? Pump operates for short period, then loses prime

?? Excessive noise from wet end

?? Excessive noise from power end

??

??

??

???? PROBABLE CAUSES POSSIBLE REMEDIES

? Bearing contamination appearing on theraceways as scoring, pitting, scratching orrusting caused by adverse environment andentrance of abrasive contaminants fromatmosphere.

1. Work with clean tools in clean surroundings.2. Remove all outside dirt from housing before exposingbearings.3. Handle with clean dry hands.4. Treat a used bearing as carefully as a new one.5. Use clean solvent and flushing oil.6. Protect disassembled bearing from dirt and moisture.7. Keep bearings wrapped in paper or clean cloth whilenot in use.8. Clean inside of housing before replacing bearings.9. Check oil seals and replace as required.10. Check all plugs and tapped openings to make surethat they are tight.

? Brinelling of bearing identified by indentation onthe ball races, usually caused by incorrectlyapplied forces in assembling the bearing or byshock loading such as hitting the bearing ordrive shaft with a hammer.

When mounting the bearing on the drive shaft use aproper size ring and apply the pressure against the innerring only. Be sure when mounting a bearing to apply themounting pressure slowly and evenly.

? False brinelling of bearing identified again byeither axial or circumferential indentationsusually caused by vibration of the balls betweenthe races in a stationary bearing.

1. Correct the source of vibration.2. Where bearings are oil lubricated and employed inunits that may be out of service for extended periods,the drive shaft should be turned over periodically torelubricate all bearing surfaces at intervals of one tothree months.

? Thrust overload on bearing identified by flakingball path on one side of the outer race or in thecase of maximum capacity bearings, mayappear as a spalling of the races in the vicinityof the loading slot. These thrust failures arecaused by improper mounting of the bearing orexcessive thrust loads.

Follow correct mounting procedures for bearings.

? Misalignment identified by fracture of ballretainer or a wide ball path on the inner raceand a narrower cocked ball path on the outerrace. Misalignment is caused by poor mountingpractices or defective drive shaft. For example,bearing not square with the centerline orpossibly a bent shaft due to improper handling.

Handle parts carefully and follow recommendedmounting procedures. Check all parts for proper fit andalignment.

? Bearing damaged by electric arcing identifiedas electro- etching of both inner and outer ringas a pitting or cratering. Electrical arcing iscaused by a static electrical charge emanatingfrom belt drives, electrical leakage or shortcircuiting.

1. Where current shunting through the bearing cannotbe corrected, a shunt in the form of a slip ring assemblyshould be incorporated.2. Check all wiring, insulation and rotor windings to besure that they are sound and all connections areproperly made.3. Where pumps are belt driven, consider theelimination of static charges by proper grounding orconsider belt material that is less generative.
