Pump Replacement Parts

OEM spare parts for maintenance of even the oldest Tri-Rotor pump


Our industrial pumps are available in cast iron and bronze, achieve flow rates up to 240 GPM, and can pump the thickest fluids you can imagine.  Well known for its’ long life, the Tri-Rotor rotary piston pump offers 

many advantages over other positive displacement and centrifugal pump designs

 including internal gear pumps, external gear pumps, rotary vane pumps, and rotary lobe pumps.
 
All of the industrial pumps that we manufacture today are interchangeable with our original pumps. From our full in-house stock of parts, we can replace or retrofit any spare parts that you need, regardless of the age of the pump.

 

Features and Benefits of Tri-Rotor Industrial Pumps

  • Simple pumping operation…just three moving parts
  • Adjustable pump flow options…without the need to change motor speed
  • Handles all pump viscosities…from 40 to 5,000,000 SSU
  • Energy efficient pump design…two double-acting pistons & overlapping strokes
  • Low shear pump operation…gentle displacement per revolution
  • Low noise…liquid-tight internal pump parts are not in contact
  • Self-priming…when suction lift is required
  • Long service life…minimum industrial pump maintenance required
