A pump includes a pump housing having an impeller recess therein and a pump outlet and an impeller disposed in the impeller recess. First and second separate volute passages are disposed in the pump housing and are further disposed in fluid communication between the impeller recess and the pump outlet. Motive power and fluid are supplied to the impeller recess, thereby inducing fluid flow therein. The fluid flow is divided into the separate volute passages and the divided flow is recombined in a convergence passage before exiting the pump outlet.
