Abstract

A pump for liquids is provided, comprising a pump chamber in which a bucket wheel is mounted on a bearing so that it can rotate, and an electric motor with a stator and a rotor. The stator has stator laminations and coils, and is coated with plastic in some parts and an electric/electronic activation device. The pump is intended to have a long service life and at the same time require as little installation space as possible. This is achieved by the stator laminations of the stator being at least in part electroplated.
