17. Probable Causes Solutions
Incorrect direction of rotation Reverse motor.
Pump not Primed.
Insufficient NPSH available.
Expel gas from suction line and pumping chamber
and introduce fluid.
Increase suction line diameter.
Increase suction head.
Simlify suction line configuration and resuce length.
Reduce pump speed.
Fluid vaporising in suction line. Increase suction line diameter.
Increase suction head.
Simplify suction line configuration and reduce length.
Reduce pump speed.
Air entering suction line. Remake pipework joints.
Strainer or filter blocked. Service fittings.
Fluid viscosity above rated figure. Increase fluid temperature.
Decrease pump speed.
Check seal face viscosity limitations.
Fluid viscosity below rated figure. Decrease Fluid temperature.
Increase pump speed.
Fluid temp. above rated figure. Cool the pump casing.
Reduce fluid temperature.
Check seal face and elastomer temp. limitations.
Fluid temp. below rated figure. Heat the pump casing.
Increase fluid temperature.
Unexpected solids in fuid. Clean the system.
Fit strainer to suction line.
Discharge pressure above rated
figure
Check for obstructions i.e. closed valve.
Service system and change to prevent problem recurring.
Simplify dicharge line to decrease pressure.
Gland over-tightened Slacken and re-adjust gland packing.
Gland under-tightened adjust gland packing.

Pump speed above rated figure. Decrease pump speed.
Pump speed below rated figure. Increase pump speed.
Pump casing strained by
pipework.
Check alignment of pipes.
Fit flexible pipes or expansion fittings.
Support pipework.
Flexible coupling misaligned. Check alignment and adjust mountings accrdingly.
Insecure pump drive mountings. Fit lock washers to slack fasteners and re-tighten.
Shaft bearing wear or failure. Refer to pump maker for advice and replacement parts.
Insufficient gearcase lubrication. Refer to pump maker's instructions.
Metal to metal contact of
pumping element.
Check rated and duty presures.
Refer to pump maker.
Worn pumping element. Fit new components.
Suction lift too high. Lower pump or raise liquid level.
Fluid pumped not compatible
with materials used
Use optional materials.
No barrier system to prevent
flow passing.
Ensure discharge pipework higher than suction tank.
Pump allowed to run dry. Ensure system operation prevents this.
Fit single or double flushed mechanical seals.
Fit flushed packed gland.
Faulty motor. Check and replace motor bearings.
Pumping element missing Fit pumping element.
