* 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.

5.2.5
Lubrication schedule
5.2.5.1 Oil lubricated bearings
Normal oil change intervals are 4 000 operating hours
or not more than 6 months. For pumps on hot service
or in severely damp or corrosive atmosphere, the oil
will require changing more frequently. Lubricant and
bearing temperature analysis can be useful in
optimizing lubricant change intervals.
The lubricating oil should be a high quality mineral oil
having foam inhibitors. Synthetic oils may also be
used if checks show that the rubber oil seals will not be
adversely affected.
