Dry screw pump

Dry screw pump Product Advantage

A full range of pumps with pumping speeds ranging from 100 to 630 m ^ 3 ^ H
Optimum Limit Vacuum and Wide Range Applications
Absolute drying and oil-free
High pumping speed at atmospheric pressure reduces pumping time
Water cooling with temperature monitoring
Lower energy costs due to efficient internal compression
Dynamic wear-free seals
Direct airflow and optimized temperature curve to minimize deposition
Low energy consumption, low noise
Various accessories

Dry screw pump applications: Metallurgy, Coating, Freeze Drying, Loading Interlocking, Electron Beam Welding, Gas Separation

A special advantage is its single-chip, variable pitch rotor. They ensure efficient internal compression to reduce the energy cost requirements of pumps. This also causes heat-sensitive gases to be discharged. The dynamic wear-free seal between the bearing and the suction chamber enhances its operational safety. The innovative design and low speed of the pump realize the low load of bearings and seals.
