6.2.6 Internal coating
If the pump has an internal coating, this coating
must be inspected periodically. Any wear or cracks
of the coating found must be immediately repaired.
Failure to do this may lead to accelerated wear of
the coating during operation and corrosion of the
exposed base metal, depending on the material and
pumped liquid. Special attention must be paid to the
coating edges.
Any loss of coating material is considered to be
normal wear and tear on the pump and is not
considered as warranty. Flowserve has applied the
coatings according to the supplier's instructions but
will not be held responsible for coating wear or
cracks that may develop over time.
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
4) Part number
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.
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.
