  • Pump impeller, method of producing pump impeller, and pump with the pump impeller
    Patent number: 10907644
    Abstract: 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.
