Abstract:
A multi-switch pump assembly is disclosed that facilitates switched flow and/or mixed flow from the pump assembly. The multi-switch pump assembly comprises a pump body, an electric motor, a rotating motor shaft, a first pump stage and impeller, and a second pump stage and impeller. The first pump stage includes a first inlet and first and second outlets disposed about the pump body. The second pump stage includes a second fluid inlet connected to a mix chamber. The mix chamber further connected to the second fluid outlet of the first pump stage. The second stage further includes a second and a third outlet disposed about the pump body. An actuator connected to a valve assembly is arranged to operate and place the valve assembly into at least a first, a second, a third and a fourth switched positions to direct fluid flow between the first and the second pump stages and the first, second, third and fourth fluid outlets.
