Abstract
A centrifugal pump for conveying a fluid includes a housing having an inlet and an outlet for the fluid. An impeller is arranged in the housing for rotation in an axial direction to convey the fluid from the inlet to the outlet, a shaft extends in the axial direction for driving the impeller, and a stationary guide device for guiding the fluid from the impeller to the outlet is connected to the housing. A resilient compensating element is disposed between the housing and the guide device, is arranged around the shaft, and holds the guide device in a centered position to the impeller during a radial relative movement to the housing.
