ORDERING PARTS
The pumps covered by this manual have been designed and
built with certain replaceable wearing parts. The recom-
mended inventory of spare parts depends upon the installation
and the importance of continued operation.
For critical service requiring a minimum of “down time” a com-
plete or “quick change” rotating element is recommended.
For normal service, with repairs to be made in the field, the
following parts are recommended for stock.
1 set of bearings
1 set of casing wearing rings
1 set of casing gaskets, “O” rings and lip seals
2 mechanical seals (complete)
Parts should be ordered as far in advance of their use as pos-
sible 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.
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.)
