5.2 Pump lubricants
5.2.1 Recommended 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 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.

capacities.
5.2.5 Lubrication schedule
5.2.5.1 Oil lubricated 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
used if checks show that the rubber oil seals will not be
adversely affected.
The bearing temperature may be allowed to rise to
50 ºC (90 ºF) above ambient, but should not exceed
82 ºC (180 ºF) (API 610 limit). A continuously rising
temperature, or an abrupt rise, indicates a fault.
Pumps that handle high temperature liquids may
require their bearings to be cooled to prevent bearing
temperatures exceeding their limits.
