5.0 Commissioning
When taking delivery of a new or refurbished
pump unit it is essential to check that the
gearbox is filled with the correct quantity of oil
to the centre of the sight glass, with one of the
recommended grades of lubricant in the table
below. Failure to have the correct grade and
level of oil in the gearbox prior to installation
and start-up, could result in serious damage
to the internal components.
The oil filler cap does not require to have
vent/breather hole. Using this type of solid
filler cap prevents the ingress of dirt and
cleaning solutions that would contaminate
the lubricant and reduce or destroy its
effectiveness . If this cap is lost at any time it
is important that a replacement of the same
type is fitted immediately.
5.1 Lubricating the pump
The gearbox should be filled to the mid point
of the sight level glass. This requires
approximately 0.4 US gall of oil for a
Horizontally ported pump and 0.25 US gall for
a Vertically ported pump.
5.3 Changing the oil :-
The pump will
not
be supplied oil filled.
First change - After 150 hours of operation
or after 1 month, whichever comes first.
Subsequent changes - Every 3000 hours of
operation or annually, whichever comes first.
Only use the recommended oil types.
