The Heart of the Pump: Shaft and Bearing DesignFlowserve offers the largestshaft and bearing componentsavailable in standard ANSIpumps. The following compari-son of a Flowserve Durco Group 2 power end with that of a major competitordemonstrates the benefits ofheavy-duty design.
Bearings (see Table 1)Greater load handling ratingmeans extended MTBPM.Extended bearing life comparisonis the ratio of the load ratingsto the third power, or:
I.B.= 13 400 3
=1.43 (+43%)11 900
O.B.= 19 200 3
=1.61(+61%)16 400
The formula I=L3/D4 offers anindex of deflection to comparepump designs where:I = index of deflectionL = length of shaft overhang
from bearingD = rigid shaft diameter
Note: The Deflection Indexprovides an approximatecomparison of shaft stiffness.A detailed analysis should bemade to determine actual shaftdeflection.

43-252% greater stiffness,indicated by lower indexnumbers, results in longerMTBPM.
Flowserve Durco bearings are designed to last up to 61% longer.
Shafts (see Table 2)Solid shafts are recommendedover shaft sleeves because theyreduce the harmful effects ofdeflection and vibration.While shaft sleeves maysimplify maintenance, solidshafts reduce it.

Advanced FM SealSentryDesign Technology• Self-Flushing• Self-Venting• Self-DrainingSeal life is extended due tosuperior purging of heat, solidsand vapors. Single seals canoften be selected where dualseals or external flush andthroat bushing combinationshad been used, such as onsolids, slurry and liquorservices. Flush plans 11, 32,52, 53, etc. can be eliminated.Costs are reduced. Pumpreliability is increased.
Maximizing seal life involvesproper selection of the sealchamber and seal and glandcombination. Generally, the sealfaces should be located directlyin the flush path.

Flowserve Durco superior self-flushing seal chambers will:• Extend seal MTBPM• Improve pump reliability• Reduce costs
SealSentry FM Series
Seal Chamber
Pump Division
ANSI Pump and Enhancements
The SealSentry FM provides improved internal seal chamberflush, with better solids handling, superior heat dissipationand vapor purging. These features extend mechanical seallife in both single, internal and the process side seal of dual seals.
For best performance, select seals and glands that locatethe process side seal faces directly in the flush path.
On most applications the FM self-flush can eliminate the need for an external flush such as ANSI Plans 11 and 32.
SealSentry FM – Opportunities Results and Comments
Save on capital, power, and perhaps evaporation costs and improvesystem reliability while extending seal MTBPM.
On most applications, a bypass line such as ANSI Plan 11, which canbe subject to failure, can be eliminated. Save on capital and power costsand improve system reliability while extending seal MTBPM.
However, a bypass flush is recommended when negative suctionpressures or self-priming pumps are applied.
Note: Single external seals are discouraged particularly if solids, slurry, or liquor may be present, regardless of flush mechanism.
When a dual seal is required, such as toxic or environmental applications, seal life will be extended with SealSentry’s improvedself-flush. Longer seal MTBPM means cost savings.
On most other applications, single seals without a bypass flush may beapplied. Save on capital, avoid product contamination, and improvesystem reliability.
On some applications, single seals with a quench may be preferred.Save on capital cost, reduce contamination, and improve systemreliability while extending seal MTBPM.
When extremely abrasive and high concentration slurries exist, dualseals that isolate the seal chamber may be preferred.
Dual seals are often specified on solids, slurry, and liquorservices due to difficulties in properly flushing single seals.External flush on these dual seals adequately lubricatesinternal/external seal faces, but seal life can be reduced byprocess buildup and temperature rise on the internal sideseal. This is caused by poor process circulation.
SealSentry FM improves internal process seal flush andallows consideration of single seals with potentially no otherflush required.Note: Abrasive services require careful consideration of the concentrationand hardness of the abrasive. Pump and seal metallurgy, speed, and sealselection should be reviewed with the manufacturer.

Note: Bypass flush to internal seal normally notrequired. Barrier fluid or external flush may applyto dual seals (Plans 52, 53, etc.).
Same seal and flush plan recommendations as for FML.Single seals with all types of seat mounting configura-tions can be installed. FMS design is provided for theconvenience of customers with seal standards thatinclude small glands. Secondary to the FML, Flowserverecommends the FMS.*
• Single internal, flexibly mounted seals. Uses sleeve for seal setting and fast installation
• “Sanitary-type” applications. Less prone tobacteria build upNote: Bypass flush is normally not required.
• Dual internal component seals. Isolates the sealchamber from the process. Allows less expensive sealmaterials. Recommended in tough slurry applicationsNote: Use External Flush Plan 54. Others (i.e., Plans52, 53) not recommended without close tolerancepumping mechanism.
• Single internal component or cartridge seals whenapplied with a throat bushing. Usually selected toincrease stuffing box pressure above the vaporpressure to avoid cavitation, etc.Note: Applied with Plan 11, etc.
• Dual internal component seals. Isolates the sealchamber from the process. Allows less expensive sealmaterials. Recommended in tough slurry applications.Allows for thermal convection type flush plans;however, pumping ring devices are recommendedNote: External Flush Plans 52, 53, 54
• Single internal component or cartridge seals whenapplied with a throat bushing. Usually selected toincrease stuffing box pressure above the vaporpressure to avoid cavitation, etc.
• Usually preferred over the CBL when jacketing isselected for increased effectiveness in cooling orheatingNote: Applied with Plan 11, etc.
*All seal selections perform best when the faces are locateddirectly within the flush path, particularly if solids, liquors, orslurries are present. Component seals with clamped seat glanddesigns locate the seal faces reasonably well. Flexibly mountedseat glands should include the vent and drain option to betterlocate the seal faces. The FML is always the first-choicechamber for maximum self-flush path benefits.

Flowserve Durco reverse vaneimpellers deliver unequalledefficiency and performance.This exclusive impeller designextends bearing and seal life.
Low, Predictable Seal ChamberPressure and thrust loads resultingfrom back vane pumping actionand balance holes
Low Required NPSH, lowestoverall of any standard pump
Rear Cover Plate Wear Surfaceas the flow path exits the rear ofthe impeller, placing abrasive wearon the rear cover rather than themore expensive casing
In Shop Impeller Adjustment withthe only impeller design that takesfull advantage of the back pull outfeature. Since the critical runningclearance is set between the rear ofthe impeller and the rear coverplate, both impeller and mechanicalseal settings can be done in theshop, “on the bench,” instead ofunder adverse field conditions
Repeatable PerformanceAssurance with the only impellerdesign that offers repeatability inseal chamber pressure and bearingthrust loads
Front Vane Open Style Impelleris fully interchangeable with thereverse vane impeller. Excellentchoice for stringy and certainapplications requiring highshear against the casing.

With special attention to materialsand component options Mark 3pumps can be used to handleliquids ranging in temperaturefrom as low as -130°C (-200°F)to as high as 370°C (700°F).
It is always essential that thepressure and temperature of theapplication never exceed thepressure/temperature limits ofthe pump. These limits may befound in the chart on page 30of this bulletin.
Operation at either low or hightemperatures could requiremodification of the standardpump design to provide strengthof materials for pressurecontainment and resistance tothermal shock, a method forcooling or heating pumpcomponents, mechanical sealprotection, special gaskets, and/or maintenance of pump/motorshaft alignment.
The Ultralign C-flange motoradapter is recommended on anyapplication with temperaturefluctuations of more than38°C (100°F).

Flowserve offers a family offive (5) types of pre-engineeredbaseplate designs to extendMTBPM and reduce costs.
Reducing internal stress andvibration extends MTBPM ofpump/motor packagesPump users specify rigidbaseplate designs to:• Provide torsional lateral and
longitudinal rigidity• Improve vibration dampening
through greater mass anddesign stiffness
• Protect against transit damage• Resist twisting during
installation• Maintain designed-in shaft
alignment• Reduce installation and shaft
alignment time• Reduce diaphragming or
separation from grout• Improve pump/motor/seal
MTBPM• Reduce total life cycle
pump/motor/seal costs
BaseLine can handlethe stress. Rigid design beginswith thick plate construction.Metal baseplate sizes:• 139 to 258 feature
13 mm (1/2 in) steel plate construction
• 264 to 280 feature 16 mm (5/8 in) steel plateconstruction
• 368 to 398 feature 19 mm (3/4 in) steel plateconstruction
Polybase baseplates areconstructed of 76 mm (3 in) to102 mm (4 in) solid polymerconcrete. Baseplate Types B, C,D and E are reinforced withadded structural support forimproved rigidity.
Baseplates Provide theBackbone for Extended MTBPMThe test stand provided threecorner support of the ungroutedbaseplates. The addition ofweights on the unsupportedfourth corner caused baseplate
distortion. This distortionresulted in measurable shaftmovement that can causeproblems with field installationsand negatively affect MTBPM.
The twist test is a means ofcomparing rigid baseplatedesigns. Correctly installedrigid baseplates should notexperience these twist effects.For more information aboutthe results of baseplate testingcontact the local Flowservesales representative.

Type B
Foundation or Stilt MountedFeaturing Flowserve Durco SolidPolymer Concrete Polybase™and Polybloc™ AdjustmentSystem
Polybase• Low installed cost• Superior vibration dampening• Corrosion resistant• Superior resistance to twisting
or diaphragming• Designed to be flat• Available with or without catch
basin or grout holes• Inserts can be located to
mount alternate equipmentconfiguration requirements
Solid cast reinforced polymerconstruction makes Polybaseextremely strong and rigid. Iteasily handles pump and motorloads without flexing problemscommonly associated with castiron or FRP baseplates.
Its excellent corrosion resistantproperties enable it to outper-form and outlast typical castiron or even steel baseplates.
Vibration DampingComparisonThe extraordinary vibrationdamping characteristics ofpolymer concrete significantlyreduce wear and tear on pumps,seals and motors. Greaterdampening characteristicsmean easier vibration analysisduring preventive maintenance. Polybloc™ – Motor
Mounting Block• Flatter and more
repeatable heighttolerances than steel
• Corrosion resistant• Superior vibration
dampening• Full foot support
(no overhang)• Shown with optional
Bloc-lock and fastenersupport
• Available for alternateequipment applications

Pump Division
ANSI Pump and Enhancements
Grouted Baseplate Installations• Better dissipation of vibration• Better resistance to torsional
stress• Best design if piping designed
and installed free of stressloads
• Pipe loads stress pump andcause greater misalignmentwith the motor shaft, etc.
Rigid Stilt MountedInstallations• Better relief of pipe load
stress• Pump moves to point of
least resistance• Lowest installation cost
– Base must supply addedrigidity
– Vibration levels arehigher than in groutedinstallations

The Sealmatic PrincipleThis pump does not leak whilerunning because the Sealmaticdesign utilizes a repeller, adynamic sealing device, toevacuate liquid from the sealchamber. This is accomplishedby creation of a liquid interfaceseal in the repeller chamber thatprevents leakage along the shaftduring operation. For sealingwhile the pump is stopped,three types of sealing arrange-ments are offered for maximumapplication flexibility: Check-matic end face lip seal arrange-ment; dry-running end face sealdesigns; and the packed stuff-ing box design.
The Sealmatic design is alsoavailable with unitized self-priming and recessed impellerpumps.
This family of repellers allowsthe Sealmatic to be used inapplications having a widerange of suction pressures.Hydraulic performanceconforms to the Standard Mark 3 reverse vane impellercurves.
Applications• Tough sealing
applications wherea flush is impractical
• Evaporator service• Continuously

As the priming liquid circu-lates, it re-entrains more air,creating a partial vacuum inthe suction line. The sumpliquid is then pushed upwardby atmospheric pressure.
3. Priming AchievementAfter the priming cycle hasevacuated all of the air fromthe suction pipe, the sumpliquid floods the volute, air separator and primingchamber, and pumping outof the discharge pipe begins.The Unitized Self-Priming is fully primed and now operates exactly as a standardflooded-suction FlowserveDurco pump.
4. Sump Empty, Pump StoppedWhen the pump stops, theliquid in the discharge pipingflows back through thepump, leaving the primingchamber filled with sufficientliquid for the next primingcycle. Except for the first fill-up of the priming chamber and an occasional“topping off” in dry climates,the Flowserve Durco UnitizedSelf-Priming is automatic and trouble-free.

StoppedThe casing is shown withthe initial prime liquid, whichpermanently stays in thecasing. This serves as thepriming liquid necessary toentrain the air contained inthe suction line.
2. Pump Start-UpAs the impeller spins, thepriming liquid entrains airfrom the suction pipe andis pumped into the airseparator/priming tankportion of the casing. In thischamber the air separatesfrom the priming liquid andvents out the discharge whilethe priming liquid flowsthrough the bypass slot inthe bottom of the casing andback into the impeller eye.
Costs less to buy, installand service than submersiblepumps. Utilizes the same powerend, shaft, seal chamber andimpeller as the StandardANSI Pump. Only the casingis special.

Static Suction LiftThe higher the lift, the greaterthe amount of air in the suctionpipe to evacuate and the longerthe priming time. Exampleillustrated: A 3x2US-13 pumpwith a 330 mm (13 in) impellerlifting water 3 m (10 ft) wouldtake 18 seconds (Graph A). A lift of 4.6 m (15 ft) would take 30 seconds.
Specific GravityAs specific gravity increases,priming times also increase.For example: A pump previouslylifting 3 m (10 ft) of water (1.0 sp.Gr.) is now pumping aliquid with a specific gravity of1.4. The 3 m (10 ft) actual lift x 1.4 sp.gr. becomes an effec-tive lift of 4.3 m (14 ft), for apriming time of 26 seconds. To be conservative for specific
gravities lower than 1.0, use 1.0in the equation. The practicallimit of a self-priming pump is 6.1 m (20 ft), divide thisamount by specific gravity todetermine the actual lift limit.For example: 6.1 m (20 ft) ÷ 1.4= 4.4 m (14.3 ft) maximumpossible lift.
Suction Pipe SizeThe self-priming pump primesby evacuating the air in thesuction piping. The primingtime curves are based on thevolume of air contained in apipe length equal to the actualstatic lift shown plus thatcontained in 1 m (3 ft) ofhorizontal run into the pump.The pump example lifting liquid3 m (10 ft) and horizontally 1 m (3 ft) contains 0.0188 m3
(1150 in3) of air in the suction
pipe (Graph B).Extending the pipe’shorizontal run to 2.7 m(9 ft) gives an additional0.0090 m3 (530 in3) ofair to evacuate beforeachieving prime.
16801150 x 18 sec = 26 seconds, or 8 seconds longerpriming time.
When a self-primingpump primes, a signifi-cant volume of air isevacuated from thesuction line. A self-priming pump will notwork unless there is away for the air to bevented. Flowservesuggests that a vent line be run from thedischarge as shown on the diagram to the above.

Individual pumpcurves found inBulletin P-12-102contain graphs of bothhydraulic performanceand priming time.Once a pump hasbeen selected basedon speed, efficiency,flow and head,priming times maybe determined fromthese graphs. Aspump performancevaries with RPM andimpeller diameter,priming times alsochange. Factors suchas static suction liftdistance, specificgravity and suctionpipe size also have adirect bearing uponpriming times.

Selection Criteria1. Select priming tank with
maximum design capacityequal to or greater than themaximum process flow ratefrom Table 3 on page 51.
2. Determine NPSHa for thepump, including head lossthru priming tank fromTable 1.
3. Confirm from Table 3 thatsuction lift required doesnot exceed tank capabilities.
4. Select pump to assureNPSHr of pump is less thanNPSHa of system. GoodPump Practice recommendsthe difference be 1.5 m (5 ft)or 20%, whichever is greater.
Design/Installation Criteria1. Provide suction pipe prior
to the priming tank the samesize as tank inlet and outlet.Pipe length from the tank tothe liquid level should belimited to 6 m (20 ft). Thisprovides the maximumvolume of air the tank willprime. A change in pipedimensions must not resultin greater air volume to beprimed. NPSH and submer-gence factors must also beconsidered.
2. Provide 10 diameters ofstraight suction pipe topump inlet where possible.Suction pipe between thepriming tank and pumpmay be reduced (eccentricreducer) to match pumpsuction size.
3. Install a low levelswitch in the sumpto ensure that theminimum submer-gence is maintained.The minimumsubmergencedepends on the fluidvelocity at the pipeinlet. That fluidvelocity varies withthe inlet diameter. Ifthe liquid level in thesump allows air intothe suction pipe, thetank will lose primeand the pump willempty the tank ofliquid. See Submer-gence Table 2.
4. Provide a check valveon discharge pipeto avoid siphonproblems.
5. Seal all pipe connec-tions and the pumpto prevent air ingressand loss of prime.
6. Anchor the primingtank to the foundationthrough holes in padson bottom of tanklegs. See certifieddimension prints forsize and locations.
7. Provide proper pipingsupport.

Trouble-free pump ing of solid,stringy or fibrous slurries.Delivers efficient operation andlow NPSHr.
Vortex Pumping Action is yourBest Choice for:• Erosive/corrosive slurries• Degradation sensitive crystals• Shear sensitive liquids• Stringy solids• Waste water
Impeller DynamicsThe vortex created by thespinning impeller does thepumping with less than 20%of the media actually contactingthe impeller. Abrasive wear isminimized and solids integrityis maintained. Precision-castimpellers ensure peak energyefficiency and low NPSHrequirements. Rear pump-outvanes are used as necessary to ensure low, positive sealchamber pressure and to expelsolids from the seal area, thusmaximizing mechanical sealand packing life. The impeller is set to the rear cover plate –just like the standard reversevane impeller.
Casing DynamicsThe cylindrical volute designcombined with the impellerspinning “out of the flow”minimize radial loads on theimpeller. The result is longerseal life as well as maximizedradial bearing life. The circularflow path and tangentialdischarge also contribute tomaximum pump life.
Applications• Abrasive waste water• Biological sludge• Clarifier underflow• 5% coke slurry• Diatomaceous earth
slurry• Floculant sludge• Latex• Lime mud slurry• Organic slurry• Polymer slurry• Resin slurry• Rubber crumb slurry• Sodium hydroxide• Catalyst slurry

The KW941 Pump PowerMonitor monitors and displaysactual power to the pumpoffering simultaneous protec-tion from underload andoverload operating conditions.
The KW941 helps to eliminatecostly downtime and expensivepump repairs caused by:• Dry running• Pump overloads• Cavitation• Blocked lines• Closed suction or
discharge valves• Excessive wear or rubbing
By sensing power and not justamperes, linear measurementsare given which help to elimi-nate unwanted nuisance trips.
Broad Application Range• Works on all pumps having
steady (non-pulsating) loads:centrifugal; gear; turbine;ANSI; API; paper stock;sealed; mag drive; can motor;self-priming
Easy Installation• Simple wiring procedure• Easily installed on existing
pump installations
Easy Setup and Calibration• Settings controlled from front
panel push buttons; no internaladjustments, dip switches orpotentiometers
• Large digital display for easyviewing and accurate settings
• One step calibration can beperformed without operatingpump. No need to run pumpat off-operating conditions tocalibrate power monitor
• Settings can be viewed oradjusted during normal pumpoperation
Premium Features forReliable Protection• Push buttons display horse-
power or kilowatts; automaticconversion when switchingdisplays
• Adjustable low power andhigh power set points protectpump from underload andoverload operation. Alarmscan be tripped or pumpsshut down before damage occurs
• Adjustable trip delay timersfilter out nuisance tripscaused by temporary powerfluctuations
• Adjustable start up delaytimer is particularly usefulin unloading applications
• Optional 4 to 20 milliampanalog output. Facilitatesremote displays, operatorinterface and output to PLCor DCS
• Two form C relay outputsfor low and high power trips.Outputs can be used to shutdown pump or trip alarms
• Automatic, manual andremote reset options forversatile operation
The KW941 PowerMonitor is easy to installon new or existing pumpinstallations. All connec-tions and controls arelocated at motor starterelectrical enclosure asshown above. Costlyinstrumentation wiringto the pump is eliminated.

Display/Control Module
Full Scale RangeAdjustable 0.7 to 112 kW (1 to 150 hp). To 447 kW (600 hp) using current transformer (not included).
Display3 digit, 15 mm (0.6 in) high,7 segment, red LED digitaldisplay. Red LED indicators fordisplay mode, trip delays andtrip points.
EnclosurePolycarbonate, NEMA 4X/IP66with see-through cover. Four #8(4 mm) mounting holes.Enclosure can be drilled, sawedor punched on bottom or backfor wiring access.
Power110 VAC (220/240 VAC optional),50/60 Hz @ 0.125 amperes.Power is obtained from acontrol voltage transformer (notsupplied) connected betweentwo phases of the three-phasemotor power source.
Operating Temperature-44° to 70°C (-40° to 158°F)
Adjustable Trip Set Points• High Power: When power
exceeds the trip point setting,the trip delay is activated.When the trip delay has timedout, an alarm contact relaywill trip.
At low loads, motoramperes do not changemuch with smallchanges in pump loads.Small signal changescan cause false tripsor allow equipment tooperate below thedesired minimumoperating point.
At low loads, power islinear. Small changesin pump operating loadsprovide greater signalchanges. The KW941is more sensitive topump load changes andoffers easier setup,more reliable equipmentprotection and no falsetrips.

Selection• Sizing with less than maximum
synchronous speed rpmwhere practical
• Impeller trim from 95 to 60%of maximum with 75% optimal
• Operate from 85% to 110%of BEP
• NPSHa 20% or 1.5 m (5 ft)over NPSHr, whichever isgreater
• Consider variable speedtechnology for multipleoperating point conditions
Balance• Impeller balanced to 20 gm-
mm/kg (0.011 oz in/lb), after trimming. Two-planespin balance when outsidediameter to width ratio < 6and single plane when ≥ 6
• Coupling balanced to AGMA 8(AGMA 10 over 56 kW[75 hp]). Coupling to beelastomer type for soft start
• Offset pump and motorshaft/coupling hub keyways180° and cut keys to one-halfunfilled keyway length
Installation• Level pump/base/motor –
free of soft foot conditions• Provide 10 diameters of
straight pipe to suction inlet.Flow conditioning technologymay be an option
• Rigid baseplate design– reinforced stilt– grout installed
baseplate• Grout with low shrink cement;
epoxy grout preferred• Special cleaning and primer
to bond base with epoxy-typegrout
• Piping design to assureminimal stress (fastenersinstalled without force)
Alignment • Use laser or reverse dial
indicator technology.Recommended tolerances to: parallel0.05 mm (0.002 in) FIM;angular 0.0005 mm/mm(0.0005 in/in) FIM
• Align before and afterpipe-pump bolt-up
• Specify bolting to fitwithout force to connectpump and pipe
• Consider C-flange motoradapter for pumpingtemperatures > 93°C (200°F) or hot align afterstart-up
• Consider C-flangeadapters when minimumand maximum pumpingtemperatures are morethan > 56°C (100˚F) apart
• For pumping tempera-tures > 177°C (350°F)consider centerlinemounted casing andinclude C-flange adapter> 260°C (500°F)

Operation• Develop suitable start-up
procedures and checklists• Avoid rapid closing of process
valves (no water hammer)• Use a power monitor for
minimum/maximum flowprotection
• Add minimum flow bypassas required
• Consider soft start forfrequent on-off duty
• Consider variable speedtechnology for inherent softstart, reduced RPM andincreased efficiency
• Do not run dry. Check forsubmergence conditions,particularly in batch operation.Select pump/seal typeaccordingly
• Operate spare pump everythree (3) months
Design/Specifications• Use solid shafts –
Index of Deflection:(I = L3D4) Group 1 < 75Group 2
3500 rpm < 401800 rpm < 65
Group 3 ≤ 25• Use cartridge seals designed
to reduce fretting corrosionand for proper setting 100%of time
• Maintain critical impellersetting tolerances to hold lowthrust load and seal chamberpressure
• Specify state of the art sealchamber designs that offeranti-rotation features toreduce abrasion, vaporization,heat and cavitation at themechanical seal
• Pump manufacturerto be responsible for “TotalEngineered Seal System”(TESS)
• Rigid, cast iron motor footconstruction with ≥ 182T(S)frame sizes
Note: Some items aremore critical for longerterm installations andbecome economicalwhen life cycle costconsiderations areapplied. For furtherinformation, contact aFlowserve salesperson.

Preventive Maintenance• Change lubricant at
recommendedintervals
• Protect lubricant fromcontamination
• Use sealed or “vaporblock” power endprotection andsynthetic lubricant toreduce relubricationintervals
• Maintain mechanicalseal flush environ-ment. Eliminate theneed for flush withalternate seal and sealchamber designs whenpossible
• Maintain power endand mechanical sealsin a “clean room”
• Predictive maintenance,vibration monitoringand lubricant analysisare still good practice
