The invention discloses a fylfot cutting pump. The fylfot cutting pump comprises a pump body, an impeller and a medium separation structure arranged at the front end of the impeller, wherein the medium separation structure is composed of fylfot cutters and a fixing texture cutter; the fylfot cutters are arranged at corresponding water inlets formed in the front end of the impeller; the impeller drive the fylfot cutters to rotate together so as to cut up media which enter the impeller; the fixing texture cutter is composed of inner side texture cutters and outer side texture cutters; at least one inner side texture cutter is arranged on the inner side of each fylfot cutter; and at least one outer side texture cutter is arranged on the outer side of each fylfot cutter. With adoption of dynamic design of the water inlets, the fylfot cutting pump has the characteristics that the water inlets cannot be blocked, a rotary shaft cannot be twined to cause overload of a motor, and the discharge rate of the media is large.
