When fitted with a sight glass, fill the bearing housing
with oil by unscrewing the oil filler/breather and fill
through the hole.
Grease lubricated pumps and electric motors are
supplied pre-greased. To regrease, remove the pipe
plug from both the inboard and outboard bearing
location. Apply grease through the grease nipples until
it comes out of the vent holes then reinstall the pipe
plugs. Do not over grease. Grease lubricated sealed
bearings do not require relubrication and should be
replaced on a regular maintenance scheme.
Other drivers and gearboxes, if appropriate, should
be lubricated in accordance with their manuals.

* Note that it normally takes 2 hours for bearing temperature to stabilize and the final temperature will depend on the ambient, r/min, pumpage
temperature and pump size. Also some oils have a greater viscosity index than the minimum acceptable of 95 (eg Mobil DTE13M) which may
extend the minimum temperature capability of the oil. Always check the grade capability where the ambient is less than -5 ºC (23 ºF).
† Use LSC for oil mist. Oil parameters provide flash point >166 ºC (331 ºF), density >0.87 @ 15 ºC (59 ºF), pour point of -10 ºC (14 ºF) or lower.

Note: The bearing sizes do not constitute a purchasing specification.
'A' in the double row angular contact bearing nomenclature defines the requirement of no filling slot.
Duplex back-to-back bearings at drive end may be required depending upon operating conditions and pump model.
