One-half to one cubic inch of grease is sufficient for motors 5.0 hp
and under, with proportionately more grease for greater HP motors.
•
"Sealed-for-life" bearings do not require any further
lubrication during the life of the motor. These are most
fractional motors and some integral frame motors. Always
follow motor manufacturer's lubrication instructions. Make
sure to periodically check grease fittings and drain plugs for
leaks.
•
Below, Table 2 lists recommended types of grease for both
pump and motor lubrication. These types have all been
thoroughly tested and should be used whenever possible.

•
Remove grease drain plug (if present) and the filler plug in order to
lubricate greased bearings, and then add clean lubricant until it
appears at the drain hole or along the shaft. For units that contain a
drain hole, all old grease can be cleaned out before putting new grease
in. If done, leave the drain unplugged for several minutes during the
pumping operation in order to allow excess grease to be forced out.
•
Fresh lubricant should be applied every 1 to 3 months,
depending on the severity of environment the pump is in. The
better the environment, (clean, dry, and under 100 °F) the
longer the interval, not to exceed 3 months. Make sure to not
over grease as doing so can cause premature failure.
