5.2 Pump lubricants
5.2.1
Recommended rolling element bearing oil lubricants
* 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 very low pour point and good viscosity index which extend the minimum temperature
capability of the oil. Always check the grade capability where the ambient is less than -5 ºC (23 ºF).
** If preheated pure oil mist lubrication, LCS LSO 68 or LSO 100 synthetic oils are permitted.
†
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.
*** ExxonMobil SHC 524 synthetic oil has a pour point temperature of - 54 ºC. This oil can be used for ambient temperature as low as -50 ºC.

* NLGI 2 is an alternative grease and is not to be mixed with other
grades.
** Standard pre-packed grease for fitted antifriction bearings.
5.2.3.1 Food grade grease (when applicable)
NSF H1 Klubersynth UH1 64-62 is the food grade
grease option and it is NLGI grade 2.
5.2.4 Recommended fill quantities
Refer to section 5.2.2, Rolling element bearing sizes
and grease/oil capacities.
5.2.5 Lubrication schedule
5.2.5.1 Oil lubricated rolling element bearings
Normal oil change intervals are 2 000 operating hours.
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
