ABSTRACT:
A bottom inlet submersible mixing pump includes a twin volute centrifugal pump feeding a pair of vertical passageways which in turn feed an annular chamber extending around the motor stator for cooling. The annular chamber has partial dividing walls between the chamber inlets and the chamber outlets which feed discharge nozzles so as to insure a predetermined liquid level within the chamber.
