These instructions are prepared for a pump with grease

or oil lubricated bearings and mechanical seals in the

stuffing boxes. Optional features are covered by

separate instructions sheets which are furnished when

the equipment supplied includes these features.

Many models have suffix letters in the model number.

These suffix letters have been intentionally omitted from

Table I. However, when ordering repair parts, provide

the complete model number including suffix letters and

the pump serial number; both are stamped on the pump

nameplate.
