The manual includes important information on the functioning of MAGSON magneticallycoupled centrifugal pumps and how to use, install, service and dispose of them.

In the following, the magnetically coupled centrifugal pumps are referred to as “pump”.

Before putting the pump into operation, carefully read the operating manual and makesure that it is always ready at hand to all users of the pump.

Complying with all instructions of this operating manual is an essential prerequisite toguarantee the safe operation and maintenance of the pump.

Make sure that all operators and service technicians have fully read and understood themanual before they start working at or with the pump.

2.2 Validity of data

All technical data, dimensions and indications of weight etc. were valid at the day whenthis manual went to press. Specifications listed here may differ from the actual design ofthe pump but will not modify any relevant information in principle.

2.3 Purpose

MAGSON pumps are designed to function as centrifugal pumps delivering fluids.

2.4 Use to the intended purpose

MAGSON pumps must only be used to deliver fluids of watery viscosity without coarsesolids and have to be submerged all the time for cooling. So the fluids meant to bedelivered are

# water and aqueous solutions,

# acids,

# bases,

# similar fluids free of magnetizable metal particles.

Do not use the pump to deliver

# inflammable or explosive fluids,

# solid containing or abrasive fluids,

# fluids being used to process food because the pump has not been certified accordingto FDA or EC 1935/2004 standards.

If you want to deliver solids-bearing or abrasive fluids, please contact the pump’smanufacturer.

8

2.5 Anticipated misuse

The pump is misused if

# it is used other than to the intended purpose;

# it is operated beyond its defined limits;

# it is used to deliver inadmissible fluids like fluids containing magnetizable metalparticles or coarse contaminants, for example.

2.6 Limits of use

Dimensional limits

For dimensions of the pump see ∑ Dimensioned drawings in the Appendix page 30 ff.

For technical data of the pump see ∑ Appendix page 30 ff.

Other limits

Media temperature MAU BG1 (8/110): 0 to +40°C,MAU BG2 (12/330): 0 to +70°C

Pumps made of PP must not be used at temperatures below 0°C as the material starts tobecome brittle.

2.7 Warranty and liability

The pump must only be used to the intended purpose specified by this operating manual.Inappropriate operation or insufficient service and maintenance will cancel the right to allwarranty claims.

MAGSON centrifugal pumps 11Issue 2017-01 Technical Information

4. Technical Information4.1 General description

MAGSON magnetically coupled centrifugal pumps are non-self-priming centrifugal pumpsmade of plastic and built in horizontal single-stage monoblock design. A magneticcoupling connects the pump to the motor and transmits the power of the motor to theimpeller.Pump housings, impellers, inner magnet sheaths and rear casings are made of plastic.The rear casing hermetically seals the fluid from the ambient atmosphere. Because ofmagnetic power transmission, there is no need to mechanically seal the shaft. So, incontrast to mechanically or gland sealed pumps, any leakage at the shaft is completelyimpossible. Motor and pump are hermetically sealed and supposed to be used submergedwithin the liquid.

4.2 Nameplate

The nameplate of the pump not only specifies its operating data but also its type andserial number. Please indicate all these data when making an inquiry, reordering partsand, in particular, when ordering spare parts.

For further information, contact your pump's supplier or the manufacturer.

4.3 Type codes and materials

The type code on the nameplate informs you about the pump materials in contact withfluid.κ Standard (off the shelf) ϒ possible configuration – not available

9.5 Dismantling Motor & Cable

Never disassemble motor or cable. You will lose warranty immediately. If motor or cableis damaged send the pump to manufacturer for maintenance and repair.

9.6 Assembling of the pump

9.6.1 MAU type 1

Check that motor is dry; clean O-rings off and set them as the same way as disassembly.Tighten the bolts (20) alternately and diagonally with a torque of 7,5 Nm.

9.6.2 Mau type 21. Place the O-ring for separating board (12) in the grove of the motor cover (1) and put the

separating board (11) on the motor cover (6).2. Slide the impeller (7) from the edge of the separating board (11) to the center. In this case, do

not to slide the impeller quickly to the center. The impeller (7) may be pulled toward the motormagnet (2) by magnetic force and make an impact to the separating board (11). Then, theseparating board (11) may be damaged.

3. Set the stand bolt (20) on the bottom board (23), put the strainer (21) and put the casing (13)on. In this case, install the O-ring for set bolt (18) to the stand bolt (20).

4. Install the O-ring for separating board (12) in the casing (13), and put the assembling 1 & 2on. At that time, insert the bearing of the impeller (7) with the outer diameter of the pumpshaft (14).

5. Finally, fix it with set bolts (15) & (16). In this case, set the O-ring for set bolt (18) to the nutfor set bolt (17). When setting, fix the nut or set bolt (17) firstly and fix the stand bolt (20).

a. When tighten the set bolts (15) & (16), the torque is 8 Nm.

10. TroubleshootingMalfunction Cause Elimination

The pump does not startwhen being switched on.

No voltage. Check the voltage.

The impeller jams. Check both the impeller and thefan blade of the motor for easymovement.

The magnetic couplingdisengages.

The relative density and/orviscosity of the fluid is toohigh.

Reduce the delivery rate; use astronger magnetic coupling and amore powerful motor.Reduce the impeller diameter.

The pump was switchedoff, then switched onagain before the rotorstopped completely.

Make sure that the rotor hasstopped completely before youswitch on the pump again.

The impeller jams. Open the pump head to eliminatethe obstruction.

There is a loud drumming flownoise.

Cavitation. Reduce the delivery rate of thedischarge line. Increase thesuction line diameter. Cool downthe fluid. Increase the NPSH ofthe system.

There is a loud flow noise.The starting delivery rate isinsufficient.

Wrong direction ofrotation.

Correct the motor’s direction ofrotation.

There is air in the suctionline or pump housing.

Deaerate the piping and thehousing.

Since the pump is non-self-priming, both thesuction line and the pumphousing must be filled withfluid (using a foot valve, ifnecessary).

Fill the suction line and housingwith fluid

The delivery rate is too low. Wrong direction ofrotation.

Correct the direction of rotation.

The suction and/ordischarge line is clogged.

Clear the line, open the valves.

Cavitation. Increase the NPSH of the system,see Cavitation above.

There is air in the pump. Check the suction line and seal it.

MAGSON centrifugal pumps 29Issue 2017-01 Troubleshooting

Malfunction Cause Elimination

The delivery rate is too high. Pump losses are lesssignificant than presumed.

Reduce the flow rate of thedischarge line.Reduce the impeller diameter.Use a frequency converter toadjust the motor speed.

Unusual mechanical runningnoise.

Damaged bearing of themotor.

Take the motor off the pump andcheck the motor bearings.

Foreign particle in thepump head.

Open the pump head to check it.

The pump head bearingoverheats when runningdry or hot.

Open the pump head to check it.Replace the sleeve bearing, ifnecessary.

Leakage between pump andmotor.

The pump housing isdamaged.The pump is damagedbecause of solids, dry-running or overheating*.

Make an expert dismantle thepump and eliminate the fault.

Table 4: Troubleshooting

*) Detailed information on overheating and dry-running

„Overheating“ means the excessive warming of the fluid resulting from a closeddischarge and/or suction line. As the fluid cannot leave the pump, there is no exchange offluid. The fluid remains in the pump where it permanently circulates and heats up. Thisexcessive warming may cause considerable damage to the pump and its components.

To avoid an increase in temperature, the minimum flow rate must not fallbelow 5% of the maximum delivery rate!

If a pump is „running dry“, there is either air in the pump chamber or the pump is notfilled up with fluid. Being neither cooled nor lubricated, the sleeve bearings will overheat.

As a consequence, the plastic material of the pump will also overheat resulting in a leakyrear casing out of which fluid will pass.

Do not hesitate to ask us for further information on dry running andoverheating. We will be glad to help you.
