Operating Principle

Operating Principle

Inside dry screw vacuum pumps, two screw rotors rotate in opposite directions. The pumped medium is trapped between the cylinder and the screw chambers.

There, it is compressed, and transported to the outlet. During this process, the screw rotors do not come in contact with each other or the cylinder.

Cooling can be achieved through air or water cooling.
