a) Remove the bearing housing from the rotor
assembly.
b) Brush the bearing housing with hot kerosene (100
to 115 °C/212 to 240 °F) or other non-toxic solvent.
c) Clean and flush out the housing with a light mineral
oil.
d) Do not use waste oil to clean the housing.
To clean the bearings:
a) Wipe off as much grease as possible with a clean
lint-free cloth.
b) Brush bearings with hot kerosene (80 to 90 °C/ 175
to 195 °F) while gently spinning the outer bearing
ring.
c) Spin each ball to ensure that it is clean.
To remove badly oxidized grease which refuses to
come off:
a) Support the rotor in a vertical position and immerse
the bearing in hot kerosene or a mixture of alcohol
and light mineral solvent.
b) Gently spin the bearing outer ring.
c) Dry and reflush the bearing with clean light oil.
d) It is important not to under or over grease the
bearings as this will lead to over heating and
premature failure. It is recommended that the
bearings be filled with grease using a suitable
spatula. In addition the housings should be no
more than half filled.
6.3 Spare parts
6.3.1 Ordering of spares
Flowserve keep records of all pumps that have been
supplied. When ordering spares the following
information should be quoted:
1) Pump serial number
2) Pump size
3) Part name – taken from section 8
4) Part number – taken from section 8
5) Number of parts required
The pump size and serial number are shown on the
pump nameplate.
To ensure continued satisfactory operation,
replacement parts to the original design specification
should be obtained from Flowserve.
Any change to the original design specification
(modification or use of a non-standard part) will
invalidate the pump’s safety certification.

Spares should be stored in a clean dry area away from
vibration. Inspection and re-treatment of metallic
surfaces (if necessary) with preservative is
recommended at 6 monthly intervals.
