Progressive Cavity Pump

The Graco Progressive Cavity pump is a positive displacement valve that is used to move and dispense medium to high viscosity materials. As the rotor revolves, material transfers within the pump through a sequence of predetermined, discrete cavities. This provides a continuous flow while maintaining the integrity of your material.

The Advantage of Graco PC Pumps

How it works

The Progressive Cavity Pump consists of a rotor and stator that create sealed cavities for the material to flow through. As the rotor revolves inside the stator, the material is rotated through the sealed cavities in a consistent, continuous flow allowing the material to be pushed rather than squeezed, therefore not damaging the fillers or shearing the media needed for your application.
