  • Patent number: 4375943
    Abstract: 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.
