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.

Material Inlet + Universal Joint

  • The redesigned material inlet path provides less pressure restriction, minimizing dead space and pack out
  • Improved coupler stability and material chemistries of the universal joint reduce wear from abrasive materials, extending the life of the rotor and stator

Durable Rotor + Stator

  • Durable design ensures long-lasting pump life even for the most abrasive materials
  • The hardened coating prevents galling and scraping
  • Stator has wide material compatibility

Quick Release Clamp

  • New quick release clamp allows for easy removal of rotor and stator from the gear box for quick and easy cleaning and maintenance

Material Purge

  • Prime the pump faster and easier with an easily-accessible material purge location

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.
