Abstract
Disclosed is a pump having a pump rotor rotatably supported about an axis of rotation in a pump stator. In this respect, the pump rotor is designed and is arranged above a rotor shaft in a shaft bearing such that a lubricating film of a lubricating fluid formed from the pump fluid can be formed in a lubricating ring gap between the rotor shaft and the shaft bearing. In accordance with the invention, a separation device is provided at the rotor shaft by which a predefinable quantity of the ingredient can be separated from the pump fluid by means of a centrifugal force in the operating state for providing the lubricating fluid.
