Abstract

Improvements in the construction of sealing devices for vertical transmission shafts in submersible liquid pumps where the leakage chamber is located around the transmission axis, said leak collection chamber being designed to be subject to gaseous pressure, characterized in that they comprise said devices a pressure chamber surrounding the transmission shaft, whose chamber is opened in the lower part towards the liquid that is pumped and communication, on the upper part, with the leak collecting chamber.
