CONSTITUTION: A circulation pump comprises a driving body(10), the first housing(20), a rotary disk(30), an impeller, the second and third housings(50,60), a water-entering hole and a water-discharging hole. The driving body is protruded in the front. A motor is installed inside the driving body. The first housing has a connection hole(21) which is inserted into the motor shaft and a mounting part(22) at the center. An input/output is formed inside the mounting part. The rotary disk is mounted on the mounting part of the first housing. An arc-type hooking hole(31) is radially formed along the inner suface.
