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 are

recommended at 6 monthly intervals.
