* NLGI 2 is an alternative grease and is not to be mixed with other

grades.

** Factory packed bearings for the temperature range with grease

nipples.

5.2.2 Lubrication schedule

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 (131 °F) above ambient but should not exceed

95 °C (204 °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.

5.3 Direction of rotation

Ensure the pump is given the same

rotation as the pump direction arrow cast on the

pump casing.

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.

Ensure the inlet pipe and pump casing

are completely full of liquid before starting continuous

duty operation.

5.5.1 Suction pressure above atmospheric

pressure

Horizontal pumps: open vent connection (1) on top of

the pump upper casing to allow the trapped air to

escape. Let liquid run out until free from air bubbles.
