Magnetic coupling

Hermetically sealed magnetic couplings are needed if toxic, carcinogenic or hazardous conveyed fluid is being used. The liquid inside the pump is hermetically sealed from the atmosphere through a containment shell, which is located between an external magnet on the drive shaft and an internal magnet on the pump shaft. Magnetic forces cause a synchronous rotation of the pump shaft in which the torque of the drive unit is transferred from the rotating external magnets to the internal magnets.
