If a synthetic lubricant (fire resistant fluid) is to be
used instead of the normal type oil for the lubrication
of bearings, gears etc., the material of all gaskets and
"O" rings in contact with the lubricant must be
compatible with the lubricant. Normal gasket
materials will usually swell and deteriorate when
immersed in synthetic lubricants: also normal paints
will peel from internal walls of reservoirs and bearing
chambers.
In case of Pure Oil Mist lubrication the lubricant oil
should be rust and oxidation inhibited and stray mist
suppressed, manufactured in accordance with good
commercial practice. The viscosity should be ISO VG
100. Recommended Oil Suppliers are according to
the previous list

When the starting temperature is below -10 °C (14
°F) for long time it’s suggested to use synthetic oil.
Other drivers and gearboxes, if appropriate, should
be lubricated in accordance with their manuals.
In the case of product lubricated
bearings the source of product supply should be
checked against the order. There may be
requirements for an external clean supply, particular
supply pressure or the commencement of lubrication
supply before pump start-up.
5.2.4
Lubrication schedule
5.2.4.1 Oil lubricated bearings
Normal oil change intervals are 4000 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
optimising 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.
Based on the specified operating conditions and an
ambient temperature of 43°C (110°F) for ring-oiled or
splash systems, oil sump temperature below 82
°
C
(180°F) is expected.
A continuously rising temperature, or an abrupt rise,
indicates a fault.
5.3 Direction of rotation
Ensure the pump is given the same
rotation as the pump direction arrow fit on bearing
housing. In any case the direction of rotation must be
checked with the pump disconnected.
To avoid dry running the pump must either be filled
with liquid or have the flexible coupling disconnected
before driver is switched on.
If maintenance work has been carried
out to the site's electricity supply, the direction of
rotation should be re-checked as above in case the
supply phasing has been altered.
5.4 Guarding
Guarding is supplied fitted to the pump set. If
this has been removed or disturbed ensure that all the
protective guards around the pump coupling and
exposed parts of the shaft are securely fixed.
5.5 Priming and auxiliary supplies
Ensure all electrical, hydraulic,
pneumatic, sealant and lubrication systems (as
applicable) are connected and operational.
