Abstract
An apparatus includes a pump unit with a pump which is driven by a wet-rotor motor. The wet-rotor motor is surrounded by a motor housing and has a stator winding. The motor housing has a bushing arrangement for supplying power to the stator winding of the wet-rotor motor, and the bushing arrangement has, on a part of the motor housing, openings into which in each case one cable bushing is fixed with the aid of a holding element. Each cable bushing has a guide body and an insulating body. The guide body and the stator winding have a connection. The connection is formed as a press connection.
