Abstract (en)
The pump unit has a stator housing (16) which is connected to the pump housing (2). A wet-running electric motor is provided with gap tubes (18) arranged in stator housing. The plate-shaped bearing supports (26) made of sheet metal are arranged between the pump housing and the stator housing. The bearing supports are formed of centering surfaces at a distance from free circumferential edge. The centering surfaces are rested on a contact surface of pump housing in such a way that the bearing supports are centered with gap tubes relative to pump housing.
