Laminated centrifugal pump

The utility model discloses a stacked-disc centrifugal pump, which is mainly composed of a pump body and an impeller; wherein, the pump body is provided with an inlet and an outlet and further provided with at least a two stage impeller in the radial direction through the mechanical reversing gear. The utility model has rational structure and crafty design, which is characterized in that: the interval channel between the front stage outlet and the back stage outlet is relatively short, thus the medium energy is of less loss, and the circumferential direction kinetic energy of the front stage medium is adopted by the back stage impeller, so as to greatly improve the efficiency, therefore having excellent popularization value.
