FLEX PROGRESSIVE CAVITY PUMPS

A Progressive Cavity Pump (PC) is a self priming rotary positive displacement pump (displaces a fixed volume with each revolution). Progressive cavity pumps can pump a variety of fluids including viscous polymers, slurries, sludges, high solid compounds and abrasive materials.

The design consists of a single helix that rotates eccentrically in the double helix stator.

Progressive Cavity Pumps provide many features:
  • Pumping viscous materials
  • Pumping abrasive fluids
  • Pumping shear sensitive materials
  • High-pressure capability
  • High-capacity capability
  • High suction lift
  • Requires no valves
  • Self priming
  • Used in high temperatures applications
  • Handles large solids
  • Quiet, Non-pulsating operation

Stator materials such as Viton, Buna, Hypalon and EPDM and Rotor materials such as steel, chrome-plated tool steel and stainless steel enable a wide range of pumping applications and capabilities.

Progressive cavity pumps used in Municipal Wastewater, Pulp and Paper, Mining, Oil Field, Refining,  Rendering, Food Processing and Building Materials are generally installed to meter, transfer, sample, boost and grind.

FLEX Progressive Cavity Pumps offer a wide variety and range of progressive cavity pumps, packaged systems, controls and instrumentation, application and sizing support.
