Oil Lubricated Bearings
Bearing housings are fully lubricated when
shipped from the factory. Check the oil level regu-
larly and maintain it at the desired level. When lubri-
cation is required, add SAE No. 30 non-detergent
oil. Do not over-lubricate. Over-lubrication can
cause the bearings to over-heat, resulting in pre-
mature bearing failure.
Under normal conditions, drain the bearing hous-
ing once each year and refill with clean oil. Change
the oil more frequently if the pump is operatedcon-
tinuously or installed in an environment with rapid
temperature change.
Monitor the co ndition of the bearing lubri-
cant regularly for evidence of rust or mois-
ture condensation. This is especially im-
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult thefactory or a
lubricant supplier for the recommended grade of
oil.
Grease Lubricated Bearings
Bearing housings are fully lubricated when
shipped from the factory. Under normalconditions,
add No. 0 lithium base grease from a grease gun
through the grease fitting after each 250 hours of
operation or once each month, whichever comes
first. Do not over -lubricate. Over-lubrication can
cause the bearings to over-heat, resulting in pre-
mature bearing failure.
If there is no provision in the bearing cavity to drain
or flush the lubricant, the pump and bearing hous-
ing must be disassembled to completely clean and
maintain this cavity.
Under normal conditions, change the grease after
each 5000 hours of operation, or at 12 month inter-
vals, whichever comes first. Change the grease
more frequently if the pump is operated continu-
ously or installed in an environment w here variable
hot and cold temperatures are common.
Refer to the Maintenance And Repair Manual for
grease capacity of the bearing housing for the
pump.
For cold weather operation, consult thefactory or a
lubricant supplier for the recommended grade of
lubricant.
