PURPOSE: A circulating pump is provided to reduce the size of the equipment, to save cost, and to reduce the space for the equipment. CONSTITUTION: An integrally shaped pump is composed of a rotor(31), a stator(32), and a shaft(30). A method for operating the pump comprises:installing an impeller(34) for a solution pump and impellers(35), (36) for a circulating pump on the left and the right of the shaft around a motor(33); driving the motor for driving the shaft; and operating the impellers for a cooling water and a warm water by the drive of the shaft. Herein, the impellers are located in pumping blocks(37), (38), (39) for forming flowing passages in each pumping blocks.
