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.
