GEAR IRON Pump

These pump housings and mounting brackets are made from cast aluminum or bronze alloy. The rotor is made from stainless steel with a hard chrome plate for improved wear properties. The stator is made from molded Nitrile. The mechanical seal is a carbon and ceramic mechanical rotary face type for positive sealing.
The turning of the helical shaped rotor within the stationary stator creates a progressing cavity similar to a moving piston. Liquid is thus displaced generating a pumping action. Unlike piston pumping, extremely high pressure cannot be created because the stator is made of Nitrile and is flexible. Because of this flexibility contaminated liquids can be handled. High starting torque motors are recommended in order to overcome the high starting friction of the stator. The pump is relatively quiet.

ELECTRIC MOTOR MOUNTING
This pump is supplied close coupled to electric motor or as a pump alone complete with attaching parts and instructions for mounting. Any 56 frame electric motor (or 56C frame) with 58 inch shaft diameter, 1725 R.P.M. and of horsepower rating as listed can be used. The motor can be rigid or resilient mounted, sleeve or ball bearings, 50oC rise, capacitor start, counter-clockwise, rotation from shaft end.
