Abstract: Pump assemblies may include a pumping unit. The pumping unit may include at least one impeller having an impeller housing with an impeller housing intake end, an impeller housing outlet end and an impeller housing interior extending from the impeller housing intake end to the impeller housing outlet end. An impeller assembly may be disposed in the impeller housing interior of the impeller housing. The impeller assembly may include an impeller hub. At least one impeller screw blade may extend from the impeller hub. An impeller shaft may drivingly engage the impeller hub for rotation of the impeller assembly in the impeller housing interior. The impeller shaft may be configured for driving connection to the power unit.

Abstract: A high capacity flood pump system includes a floodwater diversion pathway; a pump assembly above the floodwater diversion pathway, the pump assembly including a flood pump having a pump housing with a pump housing inlet and a pump housing outlet; an impeller housing disposed in fluid communication with the pump housing between the pump housing inlet and the pump housing outlet, the impeller housing disposed beneath the pump housing; at least one impeller disposed in the impeller housing; and a power unit drivingly engaging the at least one impeller.

Abstract: A flood pump includes a pump housing having a pump housing inlet and a pump housing outlet, an impeller housing disposed in fluid communication with the pump housing between the pump housing inlet and the pump housing outlet, an impeller disposed in the impeller housing, a power unit drivingly engaging the impeller, a diversion conduit disposed in fluid communication with the pump housing between the pump housing inlet and the pump housing outlet and a pump housing outlet valve in the pump housing between the diversion conduit and the pump housing outlet.

Abstract: A tile flood pump for attachment to a tile or drain pipe and pumping water from a field. The pump includes a pump housing, a flange bolted to the tile and an impeller housing enclosing one or more, lower rotating impellers, and extending into the pump housing for pumping water from the field through the impeller housing and the tile. A flapper valve can be provided on the intake end of the pump housing to facilitate flow of water through the pump housing and the tile. A shaft housing extends into the pump housing for enclosing a drive shaft that mounts the lower impeller(s) and connects to an external drive system. A shaft housing extension is removably fitted into the shaft housing for enclosing an upper impeller to flood and cool the upper marine and load bearings which carry the impeller shaft, upon which the upper impeller is mounted.

Abstract: A tile flood pump for attachment to a tile or drain pipe and pumping water from a field through the tile or drain pipe to a drainage ditch or canal. The tile flood pump is characterized by a pump housing fitted with a flange for removably bolting to the existing tile or pump embedded in a levee or dike separating the field from the drainage canal and an impeller housing enclosing one or more shaft-mounted, lower rotating impellers, the impeller housing typically having impeller housing flanges for access to the lower impeller(s) and extending into the pump housing in angular relationship for pumping water from the field through the impeller housing and the tile, into the ditch.

Abstract: A tile flood pump for attachment to a tile or drain pipe and pumping water from a field through the tile or drain pipe to a drainage ditch or canal. The tile flood pump is characterized by a cylindrical pump housing fitted with a flange for removably bolting to the existing tile or pump embedded in a levee or dike separating the field from the drainage canal and a cylindrical impeller housing enclosing one or more shaft-mounted rotating impellers, the impeller housing extending into the pump housing in angular relationship for pumping water from the field through the pump housing and the tile and into the ditch. A pump housing flapper valve on the intake end of the pump housing can be selectively open or closed by a control rod mechanism to facilitate a flow of water by direct drainage through the pump housing and the tile into the ditch, or for pumping water through the impeller housing, the pump housing and the tile when the water in the ditch is at a higher level than the water in the field.
