PROBLEM TO BE SOLVED: To provide a storage/drainage pump using air flow, air pressure, and the like. SOLUTION: The storage/drainage pump is constituted of an air pump section, in which an upper casing cover formed with an air suction port and an air discharge port incorporates an upper casing provided with a projection connected to the air discharge port, an air impeller mounted inside, and an air inflow port, and a water pump section, in which a lower casing cover formed with a water suction port and a water discharge port incorporates a lower casing provided with a projection connected to the water discharge port, a water impeller mounted inside, and a water inflow port. The water impeller rotates in conjunction with the rotation of the air impeller to withdraw or discharge water. COPYRIGHT: (C)2004,JPO
