A rotary shearing pump for circulating liquids containing solid substances in suspension. The pump rotor comprises a hydraulic wheel and a shearing wheel which are assembled in detachable manner and each provided with curved vanes, the vanes of the shearing wheel being joined to those of the hydraulic wheel. The vanes of the shearing wheel cooperate with at least one radial blade for grinding the solid substances and preventing clogging of the pump. The vane profiles of the hydraulic wheel are designed solely in accordance with hydrodynamic conditions. The inlet edges of the shearing-wheel vanes are located on a conical surface which is coaxial with the rotor.
