A mixing pump device (1) used for fuel cells etc. has two inflow paths (51, 52), inflow side active valves (21, 22) arranged at the two inflow paths (51, 52), respectively, a pump chamber (11) into which liquids flow via each of two inflow paths (511, 522), four outflow paths (61, 62, 63, 64) for allowing a liquid mixed in the pump chamber (11) to flow out, and outflow side active valves (31, 32, 33, 34) arranged at the four outflow paths (61, 62, 63, 64), respectively. The inflow paths (511, 522) are opened in the directions where turbulent flow and/or swirl flow is formed in the pump chamber (11). The construction prevents a variation in the concentration of the liquid allowed to flow out of the outflow paths (61, 62, 63, 64) after the mixing in the pump chamber (11). |
