Pump for immersion within a fluid reservoir
View Patent ↗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.

8. The pump according to claim 7 , wherein the inlet comprises a single central opening having a diameter that is at least a third of a diameter of the housing.
9. The pump according to claim 1 , wherein the pump further comprises an agitator nozzle in fluid communication with the conduit for directing a portion of the fluid in the conduit outwardly from the pump back to a surface of the fluid reservoir.
10. The pump according to claim 9 , wherein the agitator nozzle is connected to the fluid conduit by a rotatable nozzle body and is rotatable about the longitudinal axis.
11. The pump according to claim 10 , wherein the pump further comprises a nozzle orientation means for adjusting an exit trajectory of the nozzle.
12. The pump according to claim 10 , wherein the nozzle or nozzle body further comprises a means for controlling a fluid flow rate through the nozzle.
13. The pump according to claim 1 , wherein the fluid outlets direct fluid upwardly from the housing at an angle of from 20 to 70 degrees relative to a plane of rotation of the impeller.
14. The pump according to claim 1 , wherein the fluid outlets are arcuately shaped.
15. The pump according to claim 1 , wherein the combiner directs fluid from the outlets upwardly along the body towards a bottom end of the fluid conduit.
16. The pump according to claim 1 , wherein the housing and the impeller cooperate to direct fluid tangentially and upwardly into the fluid outlets.
17. The pump according to claim 1 , wherein the fluid conduit is telescoping.
18. The pump according to claim 1 , wherein the three fluid outlets are evenly spaced apart about the housing.
19. The pump according to claim 1 , wherein the fluid outlets are upwardly oriented.
20. The pump according to claim 1 , wherein at least a portion of each fluid outlet is on a top of the housing.
21. The pump according to claim 20 , wherein the fluid outlets receive fluid flowing upwardly out of the housing.
22. 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.
23. The pump according to claim 22 , wherein each fluid outlet has an opening area that is larger at the housing and transitions to a smaller opening area.
