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.

An eddy pump impeller comprising:
- 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 having an outer surface essentially parallel to the rotational axis of the hub, inversely tapering from the hub, such that each of the plurality of blades has a width adjacent the hub that is less than a width adjacent the outer surface, and having a front surface tapering in height, such that the plurality of blades is configured to cause an eddy current and cause a fluid stream to be forced to an outside of the impeller wherein each of the plurality of blades inversely tapers at an angle of between 5 and 20 degrees.
