A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means 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 may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump has a frame, a fluid conduit coupled to the frame, a housing located at a bottom end of the liquid manure pump configured to be immersed in a liquid manure reservoir, a combiner for creating a liquid manure connection between at least two liquid manure outlets of the housing and the fluid conduit. an impeller located within the housing, a drive shaft connected to the impeller, and an agitator nozzle, in fluid communication with at least one of the liquid manure outlets, for directing a portion of the liquid manure outwardly from the pump.

A centrifugal pump with adaptive pump stages includes an impeller configured to provide kinetic energy to fluid flow through the pump. The impeller has multiple geometric dimensions. The pump includes a diffuser connected to the impeller that is configured to convert the kinetic energy provided by the impeller into static pressure energy to flow the fluid through the pump. The pump includes an adaptive material attached to the impeller that is configured to modify, during operation of the pump, a geometric dimension to modify fluid flow through the pump.
