The invention relates to a holder for fastening at least one pump in a motor vehicle, comprising an elastic damping element with an inner ring and an outer ring, wherein the inner ring and the outer ring are connected to one another via at least one connecting element, wherein the inner ring is provided for receiving the pump and the outer ring is provided for receiving a holding element for mounting on the matching counterpart in the vehicle.

Holder for fastening a pump

A pump impeller consisting of at least three different material regions, wherein an impeller wheel with a hollow shaft defines a first material region, a bearing component defines a second material region, and a permanent magnet defines a third material region. The invention furthermore relates to a method for producing the pump impeller, and to a centrifugal pump with the pump impeller. The object of the invention is to provide a robust construction, optimal venting, secure attachment of the bearing component, economic production, and a possibility of axial length tolerance compensation given a pump impeller with plastic-bonded permanent magnets. Furthermore, an optimally accurate unbalance-reduced connection between the bearing component and the magnet material should be producible.
