Abstract
A submergible liquid pump is provided with a leakage-collecting chamber arranged around the drive shaft. The leakage-collecting chamber is defined by a stationary wall and by a wall rotating with the drive shaft. Leakage hurled outwards during operation of the pump is collected with a means arranged in the leakage-collecting chamber and thus removed from the leakage-collecting chamber.
