ABSTRACT:
A pump having a main shaft which is rotatably supported in a support housing via support bearings. The support bearings are provided with passages which are connected via discharge openings with the space around the pump. As a result, no pressure can build up between the support bearings and a bearing disposed at the lower end of the shaft. Medium which during operation of the pump gets by the seals and the support bearings can flow off out of the pump through these passages and the discharge openings.
