Abstract
A single piece impeller that includes an integrally formed hub, back plate, inlet support ring and a plurality of impeller blades. The impeller blades each extend radially from an inner, leading edge to an outer, trailing edge. An extended portion of each impeller blade extends past the outer edge surface of the back plate such that the extended portion is not support along a lower edge surface. The top edge surface of the extended portion of each impeller blade is integrally formed with the support ring. The support ring provides support for each of the impeller blades and is sized to allow the single piece impeller to be removed from a mold.
