Synchronous drain pumps are highlighted in a brochure from Hanning Elektro-Werke GmbH & Co. KG. According to the company, its drain pumps are designed for use in washing machines and dishwashers. Technical features of the pump include an encapsulated coil to protect the pump against humidity and an encapsulated magnet to avoid chipping of the material, which could result in pump blockage. The pump's double-seal lip is said to prevent aggressive detergent from entering the rotor chamber and bearing area, which can lead to an early bearing failure. Technical data is provided for each pump model, along with dimensional drawings.
