6.2.1 Standard maintenance

Roller bearing

The bearings fitted are prepacked with grease at
the factory. When the regreasing period is reached
it is necessary to remove as much of the old
grease as possible with a clean lint free cloth and
repack the bearings with fresh grease.

6.2.2 Routine inspection (daily/weekly)

The following checks should be

made and the appropriate action taken to remedy
any deviations:

a) Check the behavior of the pump while running:

noise level, vibrations, bearings temperature,
flow rate and pressure.

b) Motors with sealed for life bearings require no

maintenance. If grease nipples are fitted,
check running hours since last recharge of
grease or carry out a grease change.

6.2.3 Periodic inspection (six monthly)

a)

Check foundation bolts for

security of attachment and corrosion.

b) Check pump-running records for hourly usage

to determine if bearing lubricant requires
changing.
