Twin screw pumps HTS Series
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

Materials
Casing materials
Wide selection of alloys and stainless steels, including corrosion-resistant options for harsh environments.
Standard Stainless-Steel gear casing.
Extremely tough with smooth design to avoid pocket.
Allow the installation of 1 radial bearing and 4 angular bearing per shaft, permit max pressure load at both sense of rotation
Seal Shaft Materials
Steel and special alloy materials with advanced coatings to ensure long-lasting durability and resistance.
Materials of Rotors
Dynamically balanced Rotors for high speed.
Hardened for abrasive product.
Option to have rotors with four different pitch configurations, depending on the type of product to be pumped. Different pitches allow different flow rates, pressure and solid handling.
kolsterized rotors
Connections
Wide range of fitting standards are available:
DIN 11851, DIN 11864 or Clamp ISO, ASME and other upon request
Sealing Systems

Drive Cover
- Dynamically balanced rotors for high-speed operation.
Hardened for abrasive products.
Different pitches allow for various flow rates, pressures, and solid handling. - A wide range of adaptation standards is available:
DIN 11851, DIN 11864, or Clamp ISO, ASME, and others on request.
Standard stainless steel gearbox.
Extremely linear design to prevent stagnation. - Allows the installation of 1 radial bearing and 4 angular contact bearings per shaft, ensuring maximum pressure load in both rotation directions.
- Inspection port for easy and quick maintenance checks.
- Oil recirculation channels and specially designed gear geometries ensure proper lubrication of all rotating parts.
