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.

LIQUIDS & TEMPERATURES

Service life will be increased substantially if liquid pumped is clean and has lubricity value. These pumps have extremely close tolerance. Fine abrasives like sand, silt, or powders in suspension will destroy pumping ability. Liquids compatible with bronze, stainless steel, and a fluoroelastomer lip seal can be pumped. Check a chemical compatibility chart or Oberdorfer™ factory. Acrylonitrile-Butadiene (NBR) Nitrile Lip Seal (S3) available. Temperature extremes are detrimental to service life and should be avoided. Temperature range for this pump is from -20°F to 300°F. Freezing liquid in the pump can deform or damage the pump.

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. If possible, wet gears with the liquid to be pumped for the first dry start. Liquid retained in the system and gear chambers serves to wet the pump on subsequent starts.
