PUMP ARRANGEMENT

Disclosed is a pump assembly (1) at least comprising a pump (2) having a discharge side (3) and a suction side (4), and a drive unit (5) for the pump (2), the pump (2) and the drive unit (5) being arranged in a common housing (6), the drive unit (5) being an axial-flow electric drive comprising a stator (7), which is rotationally fixedly connected to the housing (6), and a rotor (8), which is rotatably arranged relative to the housing (6), a first end face (9) of the rotor (8) being oriented towards the stator (7) along an axial direction (10), the rotor (8) forming an outer pumping means (11) of the pump (2) and having a first pumping profile (13) on an inner circumferential surface (12); in a radial direction (14), an inner pumping means (15) of the pump (2) is arranged inside the rotor (8), said inner pumping means (15) having a second pumping profile (17) on an outer circumferential surface (16), said second pumping profile (17) interacting with the first pumping profile (13) to pump a fluid (18).
