摘要： A pumping system for moving a liquid, or a mixture of a liquid and one or more objects, from a collector device submerged in a body of water, to a receiving facility includes a first delivery line, a second delivery line and a pump unit. The pump unit is submerged in the body of water at a first depth below the water surface and arranged between the collector and the receiving facility. The first delivery line is fluidly connected between the collector device and a pump unit inlet. The second delivery line is fluidly connected between a pump unit outlet and the receiving facility. The collector device is arranged at a second depth and the first depth and the second depth are controllable independently of each other.

摘要： 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.

摘要： An open water pump comprises an upper casing, a lower casing, an impeller having a central shaft and a plurality of blades. Each blade has an upper portion and a lower portion. The upper casing has an upper chamber, the lower casing has a lower chamber. A plurality of inlets attached below and to a side of the lower casing, and a plurality of outlets attached to a side of the upper casing. At least the bottom portion of the lower portion of each blade which attached to the shaft gradually bends along a rotation direction of the impeller, and a ratio of a height of the lower portion of each blade to a height of the upper portion is between 1 and 5. The impeller can be allowed to draw water at a low water level, foam formed by washing liquid or food debris on the surface of water can be less likely to get into the impeller to influence the drawing of water, a sufficient amount of water can be drawn from the water inlets.
