Pump-controller interface

摘要

The pump has an electric drive and at least one coil (20) close to a housing wall (22) for contactless energy transfer from the pump to an external component (6) and/or from an external component to the pump. At least one external component is provided in the form of an auxiliary module that can be mechanically connected to the pump and that has a coil (18) corresponding to the coil in the pump for contactless energy transfer.
