Abstract
The invention discloses apparatus for supporting a submersible pump motor unit in a stilling tube. The unit is suspended from a rising main. The stabilizing means comprises a plurality of sets of self-acting locking devices each having a cam fast on a shaft pivotally mounted in a bracket which shaft also carries counterweights which bias the cams radially outwardly. Bearing plates are located on the stilling tube and the cams engage respective plates to lock the pump against lateral movement. Each set of devices consists of four devices disposed in a lateral plane equidistantly about the axis of the tube. The plurality of sets are spaced in the longitudinal direction of the pipe.
