* 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, Bearing sizes and capacities.
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.
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 which handle high temperature liquids may
require their bearings to be cooled to prevent bearing
temperatures exceeding their limits.
5.2.5.2
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 not
more than 6 months. For food grade grease the
grease change and relubrication intervals are half
that of the conventional greases.
The characteristics of the installation and severity of
service will determine the frequency of lubrication.
Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals.
The bearing temperature may be allowed to rise to
55 ºC (99 ºF) above ambient, but should not exceed
95 ºC (204 ºF). 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 ºC (350 ºF).
Never mix greases containing
different bases, thickeners or additives.
