Vacuum Pumps - Schmalz

Vacuum pumps include an eccentrically mounted impeller with lamellas (A) which are pressed against the walls of the housing by centrifugal force and thus provide a seal. As the impeller rotates, the size of each chaer (B) varies. As the chaer becomes larger, the air in it expands and the pressure drops, resulting in a partial vacuum.
