Screwline Forvacuum pumps of dry compression , The principle of operation is based on rotation Randies . In addition to the integrated rotor cooling system, standard versions of the pumps are equipped with air cooling from the outside. The compression cavity of the vacuum pump is formed by two synchronously rotating rotors and the surface of the housing. Due to the rotation of the rotors in opposite directions, the compression cavity is gradually moving from the absorption side to the exhaust side, thus carrying out the pumping process.
