Dried out screw vacuum pumps operate with two screw rotors rotating in reverse directions. This traps the medium to be pumped between your 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 styles. It also results in a lower heat load of the compressed gas.
Cooling may be Screw Vacuum Pump accomplished through a high performance air cooling technique eliminating the need of cooling water or indirect cooling technique resulting in uniform temperatures throughout the pump body, eliminating cold spots and offering a thermally stable water jacket. The advanced screw design permits best-in-class hydrogen pumping features. Water cooling may take place in type of both direct drinking water cooling or radiator cooling with air-cooled high temperature exchangers.
