Screw Vacuum Pump

Dried out 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 electrical energy consumption compared to standard screw styles. In addition, it results in a lesser high temperature load of the compressed gas.

Cooling can be achieved through a high performance air cooling technique Screw Vacuum Pump eliminating the necessity of cooling drinking water or indirect cooling method resulting in uniform temperatures through the entire pump body, eliminating frosty spots and providing a thermally stable drinking water jacket. The advanced screw style permits best-in-class hydrogen pumping capabilities. Water cooling may take place in type of both direct water cooling or radiator cooling with air-cooled temperature exchangers.
