ABSTRACT:
A motor-driven propeller is disposed within a draft tube beneath a buoyant float and is adapted to pump water upwardly through the draft tube. In one mode of operation, the pumping device functions as an aerator in that the water pumped upwardly through the draft tube flows upwardly through an opening in the float and is deflected across the upper side of the float and into the atmosphere by a diffuser plate spaced above the opening. The pumping device can be converted into a flow developer by positioning the diffuser plate beneath the opening in the float and, when the plate is so positioned, water pumped upwardly through the draft tube strikes the plate and is deflected outwardly beneath the lower side of the float.
