Abstract
A centrifugal pump for conveying a fluid, includes a pump housing, a rotor configured to convey the fluid disposed within the housing; and a stator which, together with the rotor, forms an electromagnetic rotary drive configured to rotate the rotor about an axial direction. The stator is a bearing and drive stator with which the rotor capable of being magnetically driven without contact and magnetically levitated without contact with respect to the stator. The rotor is passively magnetically levitated in the axial direction, and actively magnetically levitated in a radial plane perpendicular to the axial direction. The pump housing includes comprising a bottom and a cover, and the rotor is arranged in the pump housing between the bottom and the cover with respect to the axial direction. An indentation is disposed in the bottom or in the cover, the indentation being configured to generate a local turbulence.
