Progressive Cavity Pumps LIBERTY PROCESS

The progressing cavity LIBERTY PROCESS pumps are extremely versatile positive displacement pumps because they combine the advantages of producing a non pulsating flow and have the ability to handle products of varying viscosities, , with abrasive solids in suspension and highly abrasive products and are shear sensitive. It has low NPSH requirements and adapts to fluctuations in pressure. When combined with  frequency adjusters, it can vary and control the flow of the pump as required by the process.


  • Non-pulsating flow
  • Under shear effect
  • Modular design
  • Easy assembly and disassembly
  • Low maintenance requirements
  • ANSI flanged connections, threaded or combined
  • Sealing options: Gaskets / Mechanical Seals
  • Option for base materials: Carbon Steel / Stainless Steel
  • Rotor Materials: Chrome Plated Steel or Stainless Steel Tool
  • Stator Materials: Buna / Nitrile / Viton / EPDM / Natural Rubber and Food Grade
  • Couplings and gaskets for hardened special requirements
  • Option for Motor reducers
  • Open Hopper Progressive Cavity Pumps
