7 Troubleshooting

7.1 Operation troubleshooting

Symptom

Cause

Remedy

The pump is not delivering liq-
uid.

The pump is not primed.

Reprime the pump and check that the pump and
suction line are full of liquid.

The suction line is clogged.

Check the suction line pressure. If it is low, locate
and remove any obstructions.

The impeller is clogged.

Disassemble the impeller and remove the block-
age.

The magnet is de-coupling.

Shut down the pump and check the temperature
and viscosity of the pumped fluid. Check the mag-
nets with a breakaway torque test.

The pump is not producing
rated flow or head.

There is an air leak in the suc-
tion line.

Check for leaks and repair the lines.

The impeller is partly clogged.

Back flush the pump to clean the impeller.

The impeller rings are worn.

Replace the defective ring as required.

There is insufficient suction
head.

Make sure that the suction line shutoff valve is
fully open and the line is unobstructed. Check the
suction pressure.

The impeller is either worn or
broken.

Inspect and replace the impeller if necessary.

The rotation is wrong.

Correct the wiring.

Pump starts and then stops
pumping.

The pump is not primed correct-
ly.

Reprime the pump.

There is an air leak in the suc-
tion line.

Check for leaks and correct.

The magnet is de-coupling.

Shut down the pump. Check the temperature and
viscosity of the pumped fluid. Check the magnets
with a breakaway torque test.

There are either air or vapor
pockets in the suction line.

Rearrange the piping to eliminate air pockets.

The bearings run hot.

The bearings are not lubricated
properly.

Check the suitability and level of the lubricant.

The lubricant is cooling.

Check the cooling system.

The pump is not aligned proper-
ly.

Check the pump alignment.

Pump is noisy or vibrates.

The pump or driver is not aligned
properly.

Align the shafts.

There is a partially-clogged im-
peller causing the imbalance.

Disassemble the impeller and remove the block-
age.

There is a broken or bent impel-
ler or shaft.

Replace as required.

The base is not rigid enough.

Tighten the pump and motor hold-down bolts or
adjust the stilts. Then check the grout.

The suction or discharge piping
is not anchored or properly sup-
ported.

Anchor the piping per the Hydraulic Institute
Standards recommendations (Edition 14, centrifu-
gal pump section).

The pump is cavitating.

Increase the NPSH available.
