Pump for immersion within a fluid reservoir |
摘要 |
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. |

1. 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. |
