In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. As the rotor rotates, the disc also rotates, thus allowing the sliding plates to slide as the inner surface of the casing is eccentric. 2. When the rotor turns, centrifugal force holds the blades versus the internal wall of the stator, which makes sure that air is completely sealed. A rotor with radial, movable blade-shaped vanes is eccentrically mounted in a stator housing. A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. Fixed suction and discharge ports. Rotary vane compressors consist of a cylindrical casing, two openings - one suction and one discharge - and a rotor positioned eccentrically with respect to the casing. Reciprocating and centrifugal compressors are the most common. The robust modular pumps are sized to fit your application with very quiet operation and virtually pulsation free flow.
