high viscosity transfer pump

If the viscosity of the medium to be transported is greater than 20 cst, do not hesitate to select our two screw pumps

Gas, liquid mixed transfer

If the medium to be transported does not allow mixing, or with gas, please select our two screw pumps

The positive displacement screw pump is a type of industrial pump.They are self-priming, capable of handling high and low viscosity fluids, solids, abrasives and corrosives, and provide a low pulsation and quiet operation. They are widely used in hygienic applications such as food, beverage, dairy, pharmaceutical and personal care industries, as well as in oil and gas, marine, offshore and chemical industries.

  • Pumping structure sensitive products such as yoghurt, cheese or fruit pulp
  • Pumping fluids with solids such as chocolate, meat or fish
  • Multiple use, operate at low capacities with low RPM’s and high RPM’s for CIP cleaning
  • For applications where high viscous products, such as bitumen, molasses or lime, need to be pumped under high pressure
  • Applications where you need a pulsation free flow such as filling machines or dosing systems
