The single-phase synchronous motor which drives the drain pump has almost completely replaced the shaded pole motor which has dominated this sector for decades. This pump type is now simply referred to as a "synchronous pump".
Our HANNING synchronous drain pump is absolutely leak-proof. This is achieved by a new pump design. The dynamic sealing, used in shaded pole pumps could be eliminited. Another advantage is the better resistance to foreign objects. Due to the design, they can be cleaned away more easily because the pump can change the direction of rotation.
