GP Series Positive Displacement Gear Pumps

From free flow to 200 PSI, our rotary gear pumps are the perfect answer for recirculating, pressure boosting, filtering spraying or for the general transfer of lube, fuel, diesel and other oils in medium to high-pressure applications.



The pump end is direct coupled to standard NEMA “C” face, UL listed, totally enclosed fan cooled electric motors or for hazardous locations, Class-I Group D explosion proof electric motors. With a heavy-duty ductile iron body and long wearing, self adjusting viton mechanical seals, these pumps are self priming and operate over a wide range of viscosities, pressures and temperatures.  

Each pump is equipped with oversized oil-less
grammix iron bearings for increased durability and
longevity in industrial applications.

Our involuted “gear within a gear” design reduces
gear wear while providing a pump with minimal noise
and excellent suction characteristics.


Features Include:

  • Heavy duty ductile iron body, gears & rotor
  • Stainless steel shaft
  • Self-adjusting Viton Seal standard
  • Grammix iron bearings
  • Standard TEFC or optional explosion proof motors
  • Optional internal relief or tank return bypass available
