To provide a suction type mixing system capable of easily and surely controlling the dispersion condition of a fluid mixture, though it has a simple structure.
A first suction mixing pump Y1 has a first distribution part 70 for distributing and discharging the fluid mixture F prepared by agitating a dispersoid P and a liquid dispersion medium L and discharged from a first discharge part 12 to a first recirculation port 71b and a first discharge port 71c. The first suction mixing pump Y1 and a second suction mixing pump Y2 are series connected in a form where suction force of a second suction part 11' of the second suction mixing pump Y2 is directly applied to the first discharge port 71c and the fluid mixture F discharged from the first discharge port 71 is sucked and introduced into the second suction part 11'. A drive control part E controls a first rotary drive means M3 and a second rotary drive means M3' to relatively change the rotation speed of a first rotary blade 6 and a second rotary blade 6' and thereby, the dispersion condition of the fluid mixture F' discharged from the second discharge part 12' is controlled.
