5.2.3 Bearings–grease lubricated
MF pumps are normally furnished with grease lubricated bearings. Grease fittings are provided on the line and
thrust bearing ends of the bearing housing; see detail below. Before starting the pump, check the bearing
frame cavities for grease and add grease as necessary. For suggested frequency and grease quantity for re-
lubrication, refer to section 5.2.6.2
Proper grease lubrication is very important. Anti-friction bearings can be over-greased as well as under-
greased. After start up, remove the grease fittings or pipe plug closest to the cover and allow the excess
grease to flow out.
