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)

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.
6.3.2 Storage of spares
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.
