a housing featuring a delivery space which the housing surrounds and axially delineates on the end sides and which comprises an inlet for the fluid on a low-pressure side of the rotary pump and an outlet for the fluid on a high-pressure side of the rotary pump;

an inner rotor rotatable in the delivery space;

an outer rotor rotatable about a pump rotational axis in the delivery space and which forms delivery cells with the inner rotor; and

a circumferential bearing wall which is formed by the housing or arranged in the housing and which surrounds the outer rotor and mounts it, such that it is rotatable about the pump rotational axis, in a radial sliding contact,

wherein the rotary pump comprises one or both of (i) multiple blind pockets in the circumferential bearing wall which are radially open towards the outer rotor and (ii) multiple blind pockets in the outer rotor which are radially open towards the circumferential bearing wall, wherein the multiple blind pockets are fluidically separated from each other in the region of the radial sliding contact between the outer rotor and the circumferential bearing wall,

wherein the rotary pump comprises one or both of (i) a chamfer on a first end side of the outer rotor along its circumferential outer periphery and (ii) an inner edge transition on the circumferential bearing wall along its circumferential inner periphery on the first end side of the outer rotor, and

wherein the multiple blind pockets are arranged in an asymmetrical distribution over the circumference of the outer rotor in relation to the circumferential direction of the outer rotor.
