b) Check that there are no abnormal fluid leaks
(static and dynamic seals).
c) Check that shaft seal leaks are within acceptable
limits.

grease or complete grease change. (Certain
motors only.)

6.3 Spare parts
6.3.1 Ordering of spares
Flowserve keeps 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.

from vibration. Inspection and re-treatment of
metallic surfaces (if necessary) with preservative is
recommended at 6 monthly intervals.
