ABSTRACT:
A submersible pump having a volute fixedly connected to the discharge conduit, and a motor housing detachably connected to the volute. The impeller is coupled to the motor mounted within the motor housing, which housing has a flange adapted to fit over the top of the volute, and mate with a corresponding flange on the volute. To fix the motor housing to the volute, guide members on the volute are inserted into slots in the motor housing flange, and the motor housing twisted in one direction to engage the guide members with the slots. Twisting the motor housing in the opposite direction releases the guide members permitting the motor housing with the motor and pump impeller to be removed from the volute for servicing. A handle is provided to twist the motor housing to engage and disengage it from the volute and with which the motor and pump impeller may be lifted out of and off the volute.
To facilitate release of the guide members, the volute flange is provided with apertures, and the volute with receptacles, for inserting a tool such as a screwdriver or pipe to loosen the motor housing flange from the volute.
