Description
 
Oberdorfer Helical Rotor Pump Model# 111-UGY

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 rotary face type for positive sealing.

This pump is supplied close coupled to gasoline engine or as a pump alone complete with attaching parts and instructions for mounting. Any 2 or 4 cycle gasoline engine having a standard S.A.E. 4 bolt mounting flange and 5/8 inch shaft diameter with key slot can be used. An engine rating of at least 2.2 horsepower at 3600 R.P.M. is necessary as only about one-half of rated power is available at the recommended pump speed of 2100 R.P.M. Larger horsepower engines (3 H.P. at 3600 R.P.M.) with 5/8 inch shaft diameter and suitable flange mounting provide extra power to compensate for power losses due to carbon deposits and gumming.

FEATURES

  • Pipe size ¾
  • All Bronze or Corrosion Resistant Aluminum Construction
  • Carbon Face Mechanical Seal
  • Quiet Running Pump
  • Can Handle Contaminated Liquids
  • Nitrile Stator and Stainless Steel Rotor
  • Easily Mounted in Field to Standard Briggs & Stratton or Tecumseh Engines

DRIVE

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.

LIQUIDS & TEMPERATURES

The corrosion resistant alloys used are compatible with common liquids including water, water solutions, oils and many commercial chemicals. Severe solvents are not compatible with the Nitrile and should not be pumped.

SUCTION LIFT

Close fit of the rotor within the stator permits lifting of liquid on the suction side as high as 20 ft. High starting torque motors are recommended in order to overcome the high starting friction of the stator.
