TROUBLES
TROUBLE
PROBABLE CAUSE
REMEDY
Failure to deliver liquid or sufficient
pressure.
Pump not primed.
Pump not up to speed.
Discharge head too high.
Insufficient available NPSH.
Incorrect direction of rotation.
Air leaks in suction line or through stuffing
boxes.
Impeller passages restricted
Worn wearing rings.
Damaged impeller.
Foot valve too small or restricted by dirt.
Re-prime.
Check for low motor voltage or motor over-
load. Other drives, increase driver speed
when possible.
Check to see that all discharge valves are
opened and the discharge line is free from
obstructions. In some cases, the installation
has to be altered or a pump of suitable rating
must be provided.
Check NPSH requirements of pump and
increase system NPSH accordingly.
Check the impeller assembly for correct rotation
either by removing upper case or through
priming connection. Check rotation of driver.
Tighten packing. Check for air leaks between sleeve
and shaft and replace O-ring if there is an air leak.
Check all suction line joints
For bad gaskets and loose joints.
Disassemble the pump and clean impeller.
Replace worn parts.
Replace or repair impeller.
Replace with adequate size foot valve or clean
foot valve.
Pump loses prime after starting
Air leaks in suction line.
Insufficient available NPSH
Tighten packing. Check for air leaks between
sleeve and shaft and replace O-ring if there
is an air leak. Check all suction line joints
for bad gaskets and loose joints.
Check NPSH requirements of the pump and
increase the system available NPSH
