Abstract

An impeller assembly including a housing and an impeller is provided. The impeller is positioned within a volute of the housing and includes a hub and a plurality of blades. The plurality of blades are spaced about the hub along a circumferential direction of the impeller. The plurality of blades include a first pair of blades and a second pair blades. The first pair blades defines a first gap along the circumferential direction at a radially outer portion, and the second pair blades defines a second gap along the circumferential direction at a radially outer portion. The first gap is unequal to the second gap in order to reduce an amount of noise generated by the impeller assembly.
