ABSTRACT OF DISCLOSURE EDDY PUMP A pump is provided with a vortex generating member which rotates about a central axis to generate a vortex column of liquid which has a rotary velocity and which is directed to the pump inlet. At the pump inlet, this energy is dissipated into the ambient liquid causing an inward flow of liquid swirling in an opposite direction into and through the pump inlet for discharge through a pump outlet. These opposite directions liquid flow through the pump inlet results in the term "eddy pump". The preferred vortex generating member has a plurality of outer liquid inlets leading to passageways of reducing cross section which causes the liquid to increase in velocity as the liquid flows radially inwardly toward the axis and liquid streams are combined tangentially at the axis. Each of the accelerating streams is identical and they add and combine with one another to create the axially flowing vortex column of liquid.
