Abstract: An eddy pump impeller includes a hub and a plurality of blades. The hub has a rear surface, and tapers from the rear surface to a front end. The plurality of blades extend from the hub. Each of the plurality of blades has 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 has 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.

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.

Abstract: Improvements in an Eddy pump impeller. The Eddy pump impeller uses five blades that provides clearance for material and liquid to enter between the blades and provide optimal pumping. The five blade design provides the best balance of pumping volume and clearance for movement of material. The impeller has a tapered central hub provides to smooth transition for the material and fluid being pumped to enter into the blades of the impeller. The back of the impeller has a flattened end or back plate reduces that fluids and material from entering behind the impeller. The back plate tapers from the front tapered central hub to provide increased impeller blade surface area to smooth the transition from the leading to the trailing end of the impeller blade. The impeller has improved efficiency that reduces the electrical costs to operate a pump.
