ABSTRACT:
An underwater pumping arrangement includes a submersible pump having a pump outlet conduit provided with a first connecting flange adapted to register with a second connecting flange of an outflow conduit permanently provided at the bottom of a liquid-filled pit or container to form with the second connecting flange a seal-tight conduit joint. As the pump is lowered into the liquid-filled pit or container towards the bottom thereof, it is guided by cables or rails into a predetermined position in which the first connecting flange registers with the second connecting flange. The pump is provided at its underside with a supporting structure for directly supporting the pump upon the bottom of the pit or container when the pump has been lowered into the predetermined position. One of the two conduits is provided with an expandable-contractable connecting chamber connected to one connecting flange. When activated, the expandable-contractable connecting chamber presses the one connecting flange into seal-tight engagement with the other connecting flange to form the seal-tight conduit joint. In this way there is established between the first and second connecting flanges a seal-tight engagement whose effectiveness is not mainly dependent upon the inherent weight of the pump itself.
