Dried out screw vacuum pumps operate with two screw rotors rotating in reverse directions. This traps the moderate to become 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 in comparison to standard screw designs. It also results in a lesser temperature load of the compressed gas.
Cooling may be accomplished through a high performance air cooling technique eliminating the need of cooling water or indirect cooling method leading to uniform temperatures throughout the pump body, eliminating Screw Vacuum Pump frosty spots and offering a thermally stable water coat. The advanced screw style permits 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.
