Product Description

>DSE650 Dry Screw Vacuum Pumps

Dry screw vacuum pumps operate with two screw rotors rotating in opposite directions. This traps the medium to be pumped between the cylinder and the screw chambers and transports it to the gas discharge. The advanced screw design results in lower electric energy consumption compared to standard screw designs. It also results in a lower heat load of the compressed gas.

Cooling can be achieved through a high performance air cooling method eliminating the need of cooling water or indirect cooling method resulting in uniform temperatures throughout the pump body, eliminating cold spots and providing a thermally stable water jacket. The advanced screw design allows for best-in-class hydrogen pumping capabilities. Water cooling can take place in form of both direct water cooling or radiator cooling with air-cooled heat exchangers.

• Complete series with pumping capacity of 35 to 1100 m³/h
• Optimal ultimate pressure and broadest range of applications
• Completely dry and oil-free
• High pumping speed at atmospheric pressure reduces the pump-down time
• Water cooling with temperature monitoring
• Saving energy costs through internal compression
• Wear-free dynamic seal
• Direct gas flow and optimized temperature profile minimize deposits
• Low energy consumption, low noise level
• Extensive range of accessories
