Abstract: A housing of a single material of construction for a submersible pump adapted to integrally contain the usual diffuser stack and a mounting bracket for the pump motor. The housing is provided upwardly of the lower end thereof with a multiplicity of circumferentially arranged inwardly turned fingers, the upper edges of which constitute shoulders to support the diffuser stack and with the developed apertures constituting outlet ports for water escaping downwardly along the housing wall from the diffuser stack to prevent excessive heating within the housing during operation. The housing also contains an adapter plate at the normally lower end thereof for direct securement to the prime mover.
