摘要： A rotary pump includes a housing featuring a delivery space which the housing surrounds and axially delineates on the end sides; an inner rotor rotatable in the delivery space; an outer rotor rotatable about a pump rotational axis in the delivery space and forming delivery cells with the inner rotor; and a circumferential bearing wall which mounts and surrounds the outer rotor rotatably about the pump rotation axis in radial sliding contact. The circumferential bearing wall includes multiple blind pockets which are radially open towards the outer rotor and/or the outer rotor includes multiple blind pockets which are radially open towards the circumferential bearing wall.

摘要： A pump-motor unit includes: a housing structure; an impeller for delivering a fluid; an electric drive motor accommodated in the motor space and including a rotor coupled to the impeller in order to rotationally drive it and a stator with a stator centring structure. The housing structure includes a pump space portion, a motor space portion, a housing centring portion axially between the pump space portion and the motor space portion, and a motor space opening on an end-facing side, through which the rotor and the stator can be axially inserted into the motor space. The housing centring portion encloses the stator centring structure in order to centre the stator.
