Abstract
A pump for immersion in a fluid reservoir has an extensible body, fluid conduit and drive in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, 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 tangential fluid outlets that are upwardly angled towards the conduit. A combiner is provided to merge the outlets 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.
Claims31
A pump for immersion within a fluid reservoir comprising:
- a pump body comprising an elongated fluid conduit having a longitudinal axis;
- a housing located at a bottom end of the pump body, the housing comprising a fluid inlet and at least three tangential fluid outlets;
- a combiner for creating a fluid connection between the outlets and the fluid conduit;
- and,
- an impeller located within the housing having vanes shaped to direct the fluid tangentially within the housing.
A pump for immersion within a fluid reservoir comprising:
- a frame;
- a telescoping pump body connected to the frame, the body comprising a telescoping fluid conduit, the body and conduit extensible along a longitudinal axis;
- a frame adjustment means for pivoting the telescoping pump body from a substantially horizontal transport position to a non-horizontal working position;
- a housing located at a bottom of the pump body comprising a bottom fluid inlet and at least three tangential fluid outlets;
- a combiner for creating a fluid connection between the outlets and the telescoping fluid conduit, the combiner directing fluid from the outlets upwardly along the body and towards a bottom end of the fluid conduit;
- an impeller located within the housing having vanes shaped to direct the fluid tangentially within the housing;
- a drive means for providing power to the impeller, the drive means extensible with the telescoping pump body;
- an agitator nozzle for directing a portion of the fluid outwardly from the pump back to a surface of the fluid reservoir, the agitator nozzle rotatable about the longitudinal axis;
- and,
- a nozzle orientation means for adjusting an exit trajectory of the nozzle.
