Dried out screw vacuum pumps Screw Vacuum Pump 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 designs. It also results in a lower warmth load of the compressed gas.
Cooling may be accomplished through a high performance air cooling technique eliminating the necessity of cooling water or indirect cooling method resulting in uniform temperatures through the entire pump body, eliminating frosty spots and offering a thermally stable drinking water coat. The advanced screw style allows for best-in-class hydrogen pumping features. Water cooling can take place in type of both direct water cooling or radiator cooling with air-cooled temperature exchangers.
