High Viscosity Pumping

The ideal solution when a paste-like medium needs to be dispersed at high pressure, our high viscosity screw pump is certified for food manufacture in accordance with the “Declaration of Conformity for food processing machinery”. Its barrel, nozzle and mold can be used in the chocolate and cream making process.

  • Dispenses high viscosity fluids accurately
  • High working pressure and maximum output
  • Continuous, balanced, adjustable delivery flow within a dynamic range of viscosity and range
  • Developed for process engineering
  • Robust pump solutions for food and chemical industry

High viscosity pump diagram

The SUP screw pump is comprised of three rotors: a center rotor, which is driven by a drive shaft, and two idling side rotors driven by the center rotor. These rotors are encased in a closely fitting rotor bush. Interlocking the rotors creates sealed chambers through which the pumped media is conveyed.

When the center rotor is rotated by the drive shaft, these sealed chambers receive the medium to be pumped at the suction side of the pump and convey it in an even stream to the delivery side, at which point it is subjected to the system pressure for the application.
