PURPOSE: A pump for a microbubble generating device is provided to actively suck air according to a cavitation phenomenon generated by a centrifugal force caused by the rotation of the impellers. CONSTITUTION: A pump (1) for a microbubble generating device includes a motor (2), a water inlet (4), a drain (5), and a pump chamber. The pump chamber includes a plurality of compartments (6). One of the compartments in which a cavitation phenomenon occurs according to the rotation of the impellers (3) includes an air intake check valve which is opened/closed by the air pressure. A portion of the pump chamber where the risen air stays includes a first air sensing sensor (9) and an air discharge valve (10). The air discharge valve is composed of a solenoid valve driven by a control unit (11). The control unit receives sensing signals of the first air sensing sensor and calculates based on the preset data. [Reference numerals] (11) Control unit; (12) Auxiliary pump; (AA) Power unit
