Abstract (en)
The pump has a material comminution unit comprising movable toothed sectors (6) secured in rotation to shaft (1) and fixed toothed sectors (7) fixed on a pump body (4). The sectors are axially placed one above another and have opposite labyrinth profiles inclined from the shaft to the body in a direction from a suction orifice toward an impeller (3), so that the movable toothed sectors overlap the fixed toothed sectors at each turn with comminution clearance. Angular positions of the sectors are such that all the movable toothed sectors do not overlap the fixed toothed sectors simultaneously.
