*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.

5.5.1Suction 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.
