Abstract (en)
[origin: US2013330170A1] In a centrifugal pump for pumping a fluid with central axial suctioning and radial discharging of the fluid to be pumped out of the impeller, the impeller includes an upper cover plate and a lower cover plate and multiple interposed blades therebetween. In the radial inner region, the blades extend essentially parallel to the rotation axis of the impeller in the axial direction of the pump and thus are upright, wherein said blades in the course radially outwards thereof are increasingly inclined or extend oblique.
