TROUBLESHOOTING

Issue

Probable Cause

Remedy

�

Pump not primed.

Check that pump and suction line are full of
liquid. Reprime pump.

�

Suction line clogged/not filled with liquid

Remove obstructions/fill line.

�

Impeller clogged with foreign material.

Back flush pump to clean impeller.

No liquid delivered

�

Foot valve or suction pipe opening not

sufficiently submerged.

Consult factory for proper depth. Use baffle to
eliminate vortices.

�

Suction lift too high.

Reduce suction lift.

�

Wrong rotation direction.

Provide correct rotation

�

Air or vapor pocket in suction line.

Vent suction line.

�

Available NPSH not sufficient.

Increase available NPSH.

�

Pump not up to rated speed.

Increase speed.

�

System head too high.

Decrease system resistance.

�

Air leak thru gasket.

Replace gasket.

�

Air leak thru seal chamber

Replace or readjust packing/mechanical seal.

�

Impeller partly clogged.

Back flush pump to clean impeller.

�

Worn wearing rings.

Replace defective part as required.

Pump not producing
rated flow or head.

�

Insufficient suction head.

Ensure that suction line shutoff valve is fully
open and line is unobstructed and filled with
liquid. Vent line of vapor or air pockets.
Increase suction head.

�

Worn or broken impeller.

Inspect and replace if necessary.

�

Wrong direction of rotation.

Change rotation to concur with direction
indicated by arrow on bearing frame.

�

Available NPSH not sufficient.

Increase available NPSH.

�

Pump not up to rated speed.

Increase speed.

�

Improperly primed pump.

Reprime pump and maintain full suction line.

�

Air or vapor pockets in suction line.

Rearrange piping to eliminate air pockets.

Pump starts then
stops

�

Air leak in suction line or seal chamber.

Repair (plug) leak.

pumping

�

Air or vapor in liquid.

Deareate liquid, maintain pressure to prevent
vaporization.

�

Available NPSH not sufficient.

Increase available NPSH.

�

Improper alignment.

Re-align pump and driver.

Bearings run hot

�

Improper lubrication.

Check lubricant for suitability, quantity,
quality, and pressure. Remove dirt and moisture
from oil and bearings.

�

Insufficient cooling liquid.

Check cooling system, clean oil cooler.

�

Bearings too tight.

Replace bearings.

�

Excessive vibration

Correct cause of vibration.
