Abstract

Eine Pumpe mit einer Pumpenkammer und einem darin rotierenden Impeller weist einen Einlass in die Pumpenkammer hinein und einen Auslass heraus auf, wobei die Pumpe einen Pumpenmotor mit einem Rotor aufweist. Rotor und Impeller sind miteinander verbunden, wobei der Impeller in axialer Richtung hin zu dem Einlass abgestützt ist und wobei dafür eine axiale Abstützung gegen ein Axiallager vorgesehen ist. Dabei liegt das Axiallager auf einer Rotationsachse des Rotors und besteht aus einer zentral gelagerten konkaven Lagerschale, in der ein konvex gewölbter Lagervorsprung des Impellers anliegt.

A pump having a pump chamber and an impeller rotating therein has an inlet into the pump chamber and an outlet out, the pump having a pump motor with a rotor. Rotor and impeller are connected to each other, wherein the impeller is supported in the axial direction towards the inlet and wherein for an axial support against a thrust bearing is provided. In this case, the thrust bearing is located on a rotational axis of the rotor and consists of a centrally mounted concave bearing shell, in which a convexly arched bearing projection of the impeller is applied.
