A water pump device includes a pump housing within which is rotatably mounted a pump shaft having a rotor mounted thereon. An annular partition wall is mounted on the housing and extends into the housing so as to form a planar extension of the rotor. The rotor and partition wall define first and second substantially independent pump chambers in the housing. Two sets of impellers are mounted on the rotor, one set of the impellers extending into each of the chambers. Liquid inlet and discharge conduits communicate with each of the chambers so that a double pump is formed in the housing.
