218-13.01 ABSTRACT OF THE DISCLOSURE A sump motor is mounted in a section of pipe. The motor is a standard motor having special caps at each end of the motor shell and with the shell forming a waterproof en- closure. The caps have radially extending spacers extending out to the pipe. At each end of the pipe are reducers, the internal diameter of the small ends of which correspond to the external diameter of another, smaller standard pipe size. At the bottom a piece of pipe of the smaller size extends inwardly of the reducer to a location in juxtaposition to the pump im- peller. Various connections and mounting arrangements may be made using standard sizes of pipe. In one embodiment the pump is mounted on a vertical track and positioned above a sump. When the water rises to a level in the sump at which pumping should commence, the motor is energized and the pump is lowered along the track into the sump.
