    摘要： 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.

    摘要： The present invention relates to a sealing arrangement for a flow machine. The sealing arrangement of the present invention is applicable for sealing bearing arrangements of centrifugal pumps, mixers, blowers etc. The present invention is especially applicable in sealing a bearing assembly including two angular contact ball bearings used in back-to-back configuration. The present invention relates especially to a baffle arranged between the bearing and the bearing housing, the baffle leaving a gap between itself and the inner bearing ring for the oil to flow from the bearing to the oil channel, and from the oil channel via a groove back to the oil chamber.

    摘要： Disclosed is an energy recovering system having a first pump for pumping a fluid from a first lower level at a first lower potential energy to a second higher level corresponding to a second higher potential energy, and a turbine being located at a third level corresponding to a third potential energy being smaller than said second higher potential energy, wherein the turbine is fluidly connected to the first pump by a connecting pipe such that the fluid can be fed by the first pump via the connecting pipe from the first lower level and via the second higher level to the turbine located at the third level, where the turbine is connected to the first pump in such a way that a recovery-energy recovered from the fluid by passing through the turbine (T) is used for a drive of the concurrently operating first pump.
