ORDERING PARTS
The pumps covered by this manual have been
designed and built with certain replaceable
wearing parts. The recommended inventory of
spare parts depends upon the installation and the
importance of continued operation.
For normal service, with repairs to be made in the
field, the following parts are recommended for
stock.
ƒ 1 set of bearings
ƒ 1 set of wearing rings (if required)
ƒ 1 set of casing gaskets, quad rings and lip
seals
ƒ 2 mechanical seals (complete)
Parts should be ordered as far in advance of their
use as possible since circumstances beyond the
control of the company may reduce existing stock.
Not all parts are stocked and must be
manufactured for each order.
To facilitate rapid handling of your order for spare
parts, be sure to include the following information:
1. Serial number of the pump. (See the pump
nameplate.)
2. Name of the part.
3. Quantity of each part.
4. Material desired. (Parts will be furnished in
original materials unless specified as a
material change. All material substitutions
should be discussed with the factory.)

1. Complete nameplate data of the pump and
motor.
