PROBLEM TO BE SOLVED: To produce nanobubbles only with a mechanical element. SOLUTION: An air guide inner pipe 9 is provided on the center of a tubular casing provided with a liquid suction mouth in parallel with the casing, a rotating drive shaft 11 is passed and pivotally supported through the center of the air guide inner pipe, a suction fin 15 is attached to the rotating drive shaft below the lower end of the air guide inner pipe. The rotation of the suction fin produces a liquid flow inside the tubular casing to suck a gas in from the lower end of the air guide inner pipe into the liquid flow. The swirling flow of the gas-liquid mixing is made a straight liquid flow through a flowing water mouth 22 provided on a pump cover 14, and while the gas-liquid mixture flow is abutted to a blade of an impeller 18 at a right angle, and sheared and raked in, the agitation and shearing are repeated to produce micro-bubbles and nanobubbles.
