Abstract

A pump assembly comprises a first pump (10) having a manifold (16) with an impeller (14) for pumping fluid from a first source (12), eg a cold water supply, to an outlet (18) of the manifold. Fluid from a second source (13), eg a hot water supply, is fed by a second pump (11) to the manifold (16) of the first pump via outlet (15). The two fluids mix together in the manifold (16) of the first pump (10), the mixing being enhanced by the action of the impeller (14). A control device (20) adjusts the speeds of the two pumps to vary the fluid mixture in response to signals from a downstream sensor (19).
