In a magnetic drive rotary vane pump two pumps design are combined together: the sealless magnetic coupling and the positive displacement system with vanes.
With the magnetic coupling the torque is transmitted through contactless magnetic forces from the external magnet which is coupled to the motor shaft to the internal magnet which is connected to an impeller or rotor. This design ensures a hermetic and reliable separation between the pump and the motor making it the best solution when pumping chemicals and acids because it prevents leakage and emissions.
A rotary vane pumping system consists of vanes mounted in a rotor that rotate inside a cavity. When the rotor moves thanks to the above mentioned mag drive system, the vanes slide into and out of the rotor creating vane chambers that do the pumping work.
