POSSIBLE CAUSE
Higher than expected viscosity
losses.
Higher than expected pressures.
Fluid is colder with a higher viscosity
than expected.
Fluid sets in line and pump during
shutdown.
Fluid builds up on pump surfaces.
Pumping abrasives
Speeds and pressures higher than
rated.
Worn bearings and gears due to lack
of lubrication.
Misalignment of drive and piping.
(Excessive overhung load or
misaligned couplings.)

SUGGESTED ACTION
If within pump rating, increase drive
size.
Reduce pump speed.
Increase line sizes.
Heat fluid, insulate lines or heat trace
lines.
Increase line sizes.
Insulate lines or heat trace lines.
Install a "soft start" drive.
Install a recirculating bypass system.
Flush system with a nonsetting fluid.
Replace the pump with more running
clearances.
Larger pumps at slower speeds.
Reduce speeds and pressures by
making changes in the system.
Replace pump with a larger model with
higher pressure ratings.
Check and replace bearing and gears
as necessary. Adjust lubrication
schedule to decrease time between
lubrication.
Modify external wash down method to
reduce water entering into gear case.
Check alignment of piping and drive.
Adjust as necessary.
