Dry screw vacuum pumps are high-performance and robust dry screw vacuum pumps for process technology, demanding applications with maximum flexibility and modularity for process changes. They are used wherever gases and vapors need to be pumped reliably and without contamination. Due to dry screw technology, the compression chamber is completely free from operating fluids. This design feature minimizes process contamination and maximizes uptime by reducing maintenance intervals compared to other technologies. In practice this means no environmental emissions and no cost arise for the purchase, replacement, and disposal of operating fluids. Maintenance tasks such as oil changes or filter replacement are no longer required or are reduced to a minimum.
Reliable Pumping Speed Dry screw pumps are designed to achieve a high stable pumping speed - even at normal working pressure range of 75 to less than 1 Torr. Operationally Reliable The variable-pitch screw design and free gas discharge allow for a high degree of fluid and particle compatibility. Optimum corrosion resistance is ensured by even temperature distribution. The outstanding levels of efficiency reduce the thermal demand and increate the life cycle. Benefits
