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

Double flow, hygienic, powerful.

The HYGHSPIN Double Flow extends the range of the HYGHSPIN series for high differential pressures of up to 50 bar. It therefore enables its advantages to be also utilised for high-pressure applications.

The HYGHSPIN Double Flow is a double flow twin screw pump made of stainless steel. It has two external inlet connections and one central outlet connection. A two-sided bearing controls the shaft deflection. The axial thrust caused by the high pressures will be compensated internally. The shaft seals are arranged on the suction side. In summary, all the essential components are loaded only slightly despite the high differential pressures so that increased reliability and excellent durability result. The simultaneous utilisation of two stages also makes it possible to convey a large volume flow.

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

The HYGHSPIN Double Flow is available in sizes 90 and 125 as an option. The maximum conveying rate is approximately 100 m³/h. The differential pressure is up to 50 bar.
