HYGHSPIN Double Flow twin-screw pump – the efficient solution for high pressures

Double-flow, hygienic, high performance

The HYGHSPIN Double Flow extends the application range of the HYGHSPIN series, with high pressure differences up to 50 bar. This permits the HYGHSPIN advantages to be used also in high-pressure applications.

The HYGHSPIN Double Flow is a double-flow stainless steel twin-screw pump. It is fitted with two external inlet connections and one central outlet connection. Bearings on both ends keep shaft deflection under control. The high pressures due to axial thrust are compensated internally. Shaft seals are arranged on the suction side. In spite of the high pressure differences, all the main components are not subjected to high loads, which results in high reliability and outstanding service life. Moreover, the parallel use of two stages opens up the possibility for high volume flows.

The HYGHSPIN Double Flow is the hygienic and gentle solution for high-pressure applications.

Optionally, it comes in the sizes of 90, 105 and 125. Max. pumping volume is about 100 m³/h. Pressure difference is up to 50 bar.

Advantages at a glance
  • Pressure differences up to 50 bar
    Shaft deflection is controlled by bearings on both ends
  • Wide range of volume flows
    Two stages work in parallel, thereby permitting high volume flows
  • Long service life for bearings and shaft seals
    Axial forces are compensated internally, and shaft seals are fitted on the suction side

    Moreover, all the other advantages of HYGHSPIN twin-screw pumps apply
  • Considerable cost savings
    Reduced investment and maintenance costs
  • Best quality
    Made completely of stainless steel
  • Exceptional service-friendliness
    The pump must not be removed from the plant for maintenance work
  • Utmost flexibility
    A wide range of products, viscosities, and quantities can be handled with a single pump
  • Pumping is gentle and smooth
    Low speed, minimum pulsation, no pressure surges
  • Highest hygiene level
    No dead spaces, and particularly good flushing of the shaft seal
  • CIP and SIP:    
    Cleaning and sterilisation within the plant, use as CIP feed pump
