8. Pump Information
8.1 Drive
The pump is driven directly from the electric motor shaft by means of a flexible coupling. An
aluminum adapter connects the pump to the motor.
The adapter is a type “C–Face”.
8.2 Suction Lift
A rotary gear pump is capable of lifting water on the suction side as high as 20 feet. Though
gear pumps are self-priming, a foot valve is recommended.
A wet prime is required for the first dry start. Liquid retained in the system and gear chambers
serves to wet the pump during subsequent starts.
8.3 Rotation
The pump motor supplied by the factory has a clockwise shaft rotation as viewed from the
pump head. Reversing the motor rotation will reverse the “In” and “Out” ports.
To reverse single-phase motors, find the illustrations on the inside of the junction box cover or
on the motor name plate.
