Abstract (en)
[origin: EP2626564A1] The pump (1) has a pump rotor (4) rotatably supported around a rotational axis (A) in a pump stator (3) in an operating state, and a rotor shaft (5) arranged in a shaft feedthrough (6) such that a lubricating film of a lubricating fluid is formed in a ring gap between the shaft and the feedthrough. A separation device (7) is arranged at the shaft for separating a predefinable quantity of an ingredient from pump fluid (2) by centrifugal force for providing the lubricating fluid to the gap. A recirculation device (8) is arranged such that gas (201) is recirculated with the separation device. The separation device is designed as a separation disk.
