RGP Series positive-displacement gear pumps for oils, fuels, lubricants and viscous liquids — smooth, pulse-free, low-maintenance transfer.

Chempro RGP Series rotary gear pumps excel at transferring oils, fuels, lubricants, chemicals and other viscous liquids. Positive-displacement gear action delivers smooth, consistent flow regardless of viscosity, with reliability and minimal upkeep at the core of the design.
Meshing gears move a fixed volume every revolution — steady, pulse-free flow even with thick, high-density fluids.
Simple, robust construction with screw end connections keeps installation flexible and maintenance minimal.
