Bearing lubrication
WARNING:
Make sure to properly lubricate the bearings. Failure to do so can result in excess heat generation, sparks,
and premature failure.
NOTICE: Be certain to check the greasing on a pump that has been out of service for a long period of
time and re-grease if necessary.
Pumps are shipped without oil. You must lubricate oil-lubricated bearings at the job site.
Grease-lubricated bearings are lubricated at the factory.
The bearing manufacturer fills greased-for-life bearings with grease and seals them at the factory. You do
not need to lubricate or seal these bearings.
