Abstract

Motor-driven pump unit comprises an electric motor, an internal geared wheel pump, and a housing with an inlet (5.1.1) and an outlet (5.1.2) for a medium to be conveyed. The inlet is arranged in a peripheral wall (5.1) of the housing between two housing covers (5.2, 5.3). The outlet is arranged in the peripheral wall between the two housing covers. The flow path of the medium to be conveyed is designed so that the medium flows from the inlet through the electric motor, the internal geared wheel pump, and again through the electric motor toward the outlet.
