Abstract
A submersible sump pump includes a pump housing having a volute chamber in which a centrifugal impeller rotates about a vertical axis. The impeller draws water in axially from below from a fluid passage having a closed bottom, the fluid passage having a plurality of inlets located about the perimeter of the pump housing at an elevation above the level of the outlet from the fluid passage to the volute chamber. Thus, a bottom suction impeller arrangement is provided that prevents debris from the floor of the sump being drawn into the pump.
