Oberdorfer - 101MP Centrifugal Pump - Head Only - 8 GPM - 3 Phase
Suction Lift These centrifugal pumps are not self-priming. They must be installed below the liquid level so that the liquid flows to the pump by gravity (flooded suction). However, if a foot valve is used at the beginning of the suction line, and all air is bled from the pump by manual priming, the pump will lift on the suction side up to 15 feet. Such a system relies entirely on the non-leaking foot valve for starting capability.

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.

Liquids and 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 These centrifugal pumps are not self-priming. They must be installed below the liquid level so that the liquid flows to the pump by gravity (flooded suction). However, if a foot valve is used at the beginning of the suction line, and all air is bled from the pump by manual priming, the pump will lift on the suction side up to 15 feet. Such a system relies entirely on the non-leaking foot valve for starting capability.
Rotation
This helical rotor design demands a single rotation - clockwise when facing the pump drive shaft. Pump rotation and “in” and “out” ports are indicated on the dimension diagrams.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 5/8 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.(For Gas Engine version, see models 111-UGY/111B-UGY)
