* 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.

* NLGI 2 is an alternative grease and is not to be mixed with other
grades.
** Standard pre-packed grease for fitted antifriction bearings.

Food type grease regreasing interval is 1200 hours. (Grease not
to be mixed with non-food grade.)

Lubrication schedule
5.2.4.1
Oil lubricated bearings
Normal oil change intervals are 4 000 operating hours
or at least every 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.
The bearing temperature may be allowed to rise to
50 C (90 F) above ambient, but should not exceed
82 C (180 F). A continuously rising temperature or
an abrupt rise, indicate a fault.
5.2.4.2
Grease lubricated bearings
When grease nipples are fitted, one charge between
grease changes is advisable for most operating
conditions, ie 2 000 hours interval.
Normal intervals between grease changes are 4 000
hours or at least every 6 months.
The characteristics of the installation and severity of
service will determine the frequency of lubrication.
Lubricant and bearing temperature analysis can be
useful in optimising lubricant change intervals.
The bearing temperature may be allowed to rise to
55 C (99 F) above ambient but should not exceed
95 C (203 F). For most operating conditions a quality
grease having a lithium soap base and NLGI
consistency of No 2 or No 3 is recommended. The
drop point should exceed 175 C (350 F).
Never mix greases containing different
bases, thickeners or additives.
