A fluid pump is provided for delivering a fluid, particularly blood, comprising: a housing with a fluid inlet and a fluid outlet and a rotor, which is mounted in the housing such that it can rotate about an axis of rotation in order to deliver the fluid from the fluid inlet to the fluid outlet, the rotor being mounted in the housing by means of a mechanical bearing. A flow cross-section between the rotor and the housing has a local or partial flow cross-section minimum in the direction of the axis of rotation in the region of the mechanical bearing.

Fluid pump

A bearing assembly may be provided for mounting a rotor which can be rotated about a rotational axis. In particular, for a rotary fluid pump or rotary blood pump comprising: a main body, a bearing element which can be displaced relative to the main body in the direction of the rotational axis for receiving the rotor, and an adjusting device which is connected to the bearing element for displacing the bearing element in the direction of the rotational axis by a predefined distance, wherein the predefined distance is <=500 micrometres.

Bearing assembly and rotary fluid pump

A blood pump may be provided that includes an inlet, an outlet and a rotor for delivering fluid from the inlet to the outlet, wherein the rotor is suspended within the blood pump by radial passive magnetic forces and axially is preloaded in one direction at least by way of passive magnetic forces so that, during a fluid-delivering rotation of the rotor, the axial thrust of the rotor acts counter to the magnetic attraction acting axially in the direction of the outlet.
