Abstract: A pump is provided which includes a rotating element, and a volute housing having a fluid inlet and a fluid outlet. In operational state, the rotating element rotates, drawing fluid through the fluid inlet of the volute housing and expelling the fluid at a higher pressure through the fluid outlet. Further, the pump includes a bypass mechanism integrated, at least in part, within the volute housing and exposing in nonoperational state of the pump, a bypass path through, at least in part, the volute housing that allows the fluid to pass from the fluid inlet to the fluid outlet of the pump.
