PROBLEM TO BE SOLVED: To provide a volute pump P for mixing gas and liquid which is capable of finely foaming a gas-liquid mixed fluid in a pump. SOLUTION: In the volute pump P for mixing gas and liquid which discharges the gas-liquid mixed fluid sucked from the sucking port 14 through the discharging port 13 by the rotation of a rotary vane wheel 2, the rotary vane wheel is characterized in that a plurality of main vanes 20 are arranged on the rotary substrate 21 with an equal distance in the state that they are extended to the outer peripheral side from the rotation center side and a plurality of bubble-crushing projections 22 for shearing the bubbles of the gas-liquid mixed fluid are arranged at the outer peripheral part of the rotary substrate with an equal distance between the main vanes.
