ABSTRACT:
A centrifugal pump driven by a tractor draws material, as liquid manure, through a suction hose and discharges the material into one of two discharge hoses. A first discharge hose directs the material back into the source of material to agitate and mix the material. The second discharge hose is used to deliver material from the pump to a transport tank spreader. The pump has a housing rotatably supporting an impeller. A cone-shaped member connects the inlet side of the housing to the suction hose. The inlet end of the suction hose has a one-way door valve which allows the material to move into the suction hose and restricts reverse movement out of the suction hose. The inlet end of the suction hose has an exit opening closed with a movable cover. The cover can be moved to an open position so that material in the suction hose can drain back into the holding area. A primer pump mounted on the housing is operable to prime the pump with fluid.
