Pump requires excessive

breakers trip)
Fluid sets in line and pump
during shutdown.
Insulate lines or heat trace lines.
Install a “soft start” drive.
Install a recirculating bypass system.
Flush system with a nonsetting fluid.
Fluid builds up on pump
surfaces.
Replace the pump with more running
clearances.
Short pump service life Pumping abrasives Larger pumps at slower speeds.
Speeds and pressures higher
than rated.
Reduce speeds and pressures by
making changes in the system.
Replace pump with a larger model with
higher pressure ratings.
Worn bearings and gears due to
lack of lubrication.
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.
Misalignment of drive and piping.
(Excessive overhung load or
misaligned couplings.)
