13.0 Trouble-Shooting Pumps

This chart is designed to aid in the solution of pump and pump system problems. Once
the problem has been identified, work through the possible causes and solutions until
the problem has been corrected.

SYMPTOM

POSSIBLE CAUSE

REMEDY

No flow from
pump

-No liquid in reservoir (tank)
-Inlet line valve closed
-Inlet strainer is totally clogged with debris
-Crankshaft is not turning

-Ensure lines are connected and fill tank
-Ensure lines are connected and open valve
-Clean or replace strainer
-Check for power to drive and drive
connections

Insufficient
pressure
from pump
(ONLY)

-Pump speed is too low
-Relief valve improperly adjusted or worn
-Insufficient system resistance (worn nozzle)
-Worn pump valves
-Excessive leakage from pump packing

-Check belt tightness or power to motor
-Check relief valve and adjust setting
-Properly service system
-Inspect pump valves and repair or replace
-Adjust or replace packing or damaged parts

operation
(pump
pounds or
vibrates)

-All pump cylinders not primed
-By-pass or relief is piped back to suction
-Inlet line too long or too small in diameter
-Insufficient NPSHA causing cavitation
-Air leaks in suction line or fittings
-Vortex in tank near inlet pipe opening
-Air entering booster pump
-Pump valve stuck open or closed
-Valve assembly damaged or unseated
-Valve taper (seating area) washed out in
fluid cylinder
