Maintenance Routine

1. Routine maintenance
a. Oil checks
i. Remove the oil plug and take out a small amount of oil. The oil can be extracted easily by
tilting the pump so that the oil plug faces downward. If the oil appears discoloured or mixed
with water, a likely cause is a defective or worn mechanical seal which means that a full
refurbishment is necessary before the pump next runs.
b. Oil changes
i. Remove the oil plug and drain the oil completely. Pour the specified oil volume (quantity
available in the data tables on page 32) into the oil filter inlet.
ii. Dispose of the drained oil in compliance with the rules and laws of the location where the
maintenance is taking place.
iii. Replace the o-ring which seals the filter plug, and screw the filter plug back into the pump.
c. Power usage
i. Check the power drawn from each phase with the use of a CT type ammeter (clips around
the cable). If this has changed significantly since the pump was installed, or if one phase
has a notably higher or lower current than any of the other phases, stop the pump and speak
to the distributor / manufacturer about the issue.
