A portable pump for displacing water having a frame supported by ground contacting wheels for transport, an elongated tubular conduit with an impeller mounted therein and a drive shaft with one end connected to the impeller and the other end having a non complex universal bearing joint for detachably coupling directly to a driving motor shaft of a farm tractor or other prime mover. The drive shaft exits the tubular conduit on the underside so that the angle between the driving motor shaft and impellar drive shaft is at a minimum angle when the tubular conduit inlet end is tilted below horizontal in order to submerge the inlet end of the conduit into the water from the edge of a steep irrigation bank. This enables the portable pump with the non complex universal bearing joining to be backed onto the bank of a water source such as an irregation canal, stream, or lake. A casing around the drive shaft allows the shaft to become embedded into the crest of the bank allowing the inlet portion to be submerged.
A pumping apparatus for delivering water upwardly from a holding area and over a holding area bank includes a trailer having wheels and a trailer bed; a composite water drawing pipe including structure for telescoping from a shorter pipe transport length to a longer pipe deployment length to access water at lower levels in the holding area; a water drawing pipe movement mechanism including a mechanism for moving the drawing pipe between a transport position on top of the trailer bed and a deployed position substantially behind and angling downwardly from the trailer bed into water in the holding area. The composite water delivery pipe preferably includes a wider outer pipe and a narrower inner pipe, at least a portion of the narrower inner pipe being slidably retained within the wider outer pipe, the narrower inner pipe being mounted on an annular guiding carriage extending radially between the outer pipe and the inner pipe.
This invention relates to a self-contained mobile pump system for pumping water from irrigation ditches and the like. The pump system is hydraulically controlled for extending, retracting, and angling the pump system to accommodate various pumping positions and water levels.
