Abstract
A pump for immersion in a fluid reservoir has an extensible body and a fluid conduit. The length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. The pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump has a bottom housing with a bottom inlet and at least two, preferably at least three, tangential fluid outlets that are upwardly angled towards the conduit. The outlets may be merged with the fluid conduit. An impeller within the housing is shaped to transfer fluid tangentially and upwardly within the housing to co-operate with the upward angle of the outlets. These features reduce fluid pressure loss and thereby increase fluid flow rate through the pump for a given input power.
