Twin screw pumps HTS Series

Double screw pumps for sanitary food and pharmaceutical sectors

The HTS hygienic series represents the highest level of technology in the field of stainless steel twin-screw sanitary pumps, specifically designed to ensure optimal hygiene in the food and pharmaceutical industries.

Our pride lies in the extremely robust design of these pumps, achieved through an oversized shaft and bearings with a patented gear positioning system.

Key features of twin-screw pumps:

  • Gentle handling and reduced pulsations thanks to the axial direction of the product flow.
  • High suction capacity with low NPSHr (Net Positive Suction Head required) values.
  • No contact or friction between the rotors and the pump body, allowing dry running (only with flushed seals).
  • CIP (Cleaning-In-Place) capability and process operation with a single pump.
  • High pressure and flow rate despite the compact pump size.
  • Suitable for highly viscous liquids (up to 1,000,000 cps).
  • Capable of handling solid particles and/or abrasive products.
  • Easy and quick maintenance.
  • At request certificate 3-A Sanitary standar
  • At requet comply to EHEDG food safety
