Abstract
An eddy pump impeller includes a hub having a planar rear surface, the hub tapering from the planar rear surface to a conical front end, and a plurality of blades extending from the hub. Each of the plurality of blades has an outer surface essentially parallel to a rotational axis of the hub, inversely tapers from the hub, and has a front surface tapering in height from the front conical end, such that the plurality of blades is configured to cause an eddy current and cause a fluid stream to be forced to the outside of the impeller.
