The present invention relates to a kind of impeller pump, including rotor (1,1,1 ") have delivery elements (3,3,3 ", 4,4,4, ") which conveys at least part fluid axial rotor. Rotor is arranged in axial rotor relative to each other, having substantially compensated for axial-thrust component each other fluid and conveying fluid to be conveyed in two delivery elements or multiple groups delivery elements. Oppositions of fluid flowing do not give way jointly each other rotor radial discharge and can be commonly through spiral case (9) and utilization.
