Pump series GFP

The multi-phase pump is a combination of a standard centrifugal pump and a liquid ring pump both mounted together on 1 motor and 1 shaft. The centrifugal pump is used for pumping the liquid and brings the main performance of the pump.

When a gas-bubble starts to build up in the eye of the centrifugal impeller, it is evacuated by the liquid ring impeller.

The pump has 1 suction and 2 discharges: a main discharge of the centrifugal pump and a smaller discharge of the liquid ring pump that functions as an air and foam vent. The air/foam vent is typically connected back to the suction vessel.

  1. Monobloc execution with std IEC motors
  2. Air vent
  3. Liquid ring impeller
  4. Centrifugal impeller
  5. Clean water inlet

Application areas

The GFP multi-phase pump is typically used for foamig liquids and (viscous) liquids containing gas in the food-industry.

Offering a solution to liquids that are difficult to pump with standard centrifugal pumps. E.g. starch slurries, proteins,…



Your benefits


  • Electropolished stainless steel AISI316 and better: highly corrosion resistant
  • High pump efficiency resulting in lower energy consumption
  • Low NPSH values: less risk on cavitation
  • Monobloc construction: less floor space, easy installation and maintenance (no aligning)
  • Self-adjusting vacuum, no snifting valve required
