CENTRIFUGAL PUMP FAULT DIAGNOSIS Sympton Cause Pump won't start No power to pump Liquid too viscous or heavy Jammed impeller No discharge flow Pump not primed Discharge head too high Insufficient NPSHa Restricted flow into pump Liquid too viscous or heavy Less discharge flow Discharge head too high than expected Air leak into suction pipe Insufficient NPSHa Restricted flow into pump Wrong motor rotation Liquid more viscous than expected 10
CENTRIFUGAL PUMP FAULT DIAGNOSIS Sympton Cause Motor overheating Discharge head too low or over FLA Phase dropped out Wrong voltage Under sized motor Liquid more viscous than expected Noisy pump Insufficient NPSHa Discharge head too low Mis-aligned motor/coupling Entrained gasses Air leak into suction pipe Worn pump parts Dry bearings 11
AOD PUMP FAULT DIAGNOSIS Sympton Cause Pump won't start Air valve malfunction/siezure Obstructed fluid line Obstructed diaphragm chamber Diaphragm failure Diaphragm seal failure Insufficient inlet pressure Insufficient differential pressure Air valve system malfunction Air connected to exhaust Erractic flow Diaphragm failure on one side Valve ball not seating Suction leakage Diaphragm failure Diaphragm seal failure Air valve system malfunction 1
AOD PUMP FAULT DIAGNOSIS Sympton Cause Pump strokes Excessive suction lift - no discharge Suction line leakage Valve ball not seated correctly Suction line or strainer clogged Diaphragm failure Fluid discharged Diaphragm Failure from air exhaust Loose frontplate Intermittent stroke Over lubrication Diaphragm shaft seal failure Air valve system malfunction Valve ball not seated/obstructed 1
