Screw Vacuum Pump

Dried out screw vacuum pumps operate with two screw rotors rotating in opposing directions. This traps the medium to become pumped between the cylinder and the screw chambers and transports it to the gas discharge. The advanced screw style results in lower electrical energy consumption compared to standard screw designs. In addition, it results in a lower high temperature load of the compressed gas.

Cooling may be accomplished through a high performance air cooling method eliminating the necessity of cooling drinking water or indirect cooling technique leading to uniform temperatures throughout the pump body, eliminating cold spots and providing a thermally stable drinking water coat. The advanced screw style permits Screw Vacuum Pump best-in-class hydrogen pumping features. Water cooling can take place in type of both direct drinking water cooling or radiator cooling with air-cooled heat exchangers.
