These pumps are flanged to the end of the discharge line and entirely freely sus- pended in the water. It consists of the three-phase A.C. electric motor and the superimposed centrifugal pump. Motor and pump are rigidly assembled and have a common, integral shaft. The pump sucks the water through screen-protected lateral openings between the pump and motor and delivers it through the axial discharge connection at the upper pump end direct- ly into the discharge line.
