Dry Screw Vacuum Pumps

Dry Screw Vacuum Pumps

Dry 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 electric energy consumption compared to standard screw designs. It also results in a lower heat load of the compressed gas.

Cooling can be achieved through a high performance air cooling method eliminating the need of cooling water or indirect cooling method resulting in uniform temperatures throughout the pump body, eliminating cold spots and providing a thermally stable water jacket. The advanced screw design allows for best-in-class hydrogen pumping capabilities. Water cooling can take place in form of both direct water cooling or radiator cooling with air-cooled heat exchangers.

Dry screw vacuum pumps are highly efficient for use in many industrial applications including process applications. These models represent many years of experience in dry vacuum technology and offer key design benefits. The variable pitch and free gas outlet greatly improve the pump’s ability to handle liquid and dust carry-over. The unique temperature distribution offers resistance to corrosion. The optimized efficiency reduces the thermal load, thus increasing pump service life.
