The present invention relates to a pump for a micro-bubble generator having a self-absorption capacity, to form a pump housing integrally with the motor casing on one side of the motor, but the pump housing to maintain the water filled state even when the pump stops at all times It was developed to operate without supplying water to the pump housing every time； A motor having a rotating shaft protruding upward in the motor case； The first gear is formed integrally with the motor case, the top surface is opened, the bottom surface is blocked, and the rotation shaft of the motor protrudes to the bottom surface, and is mounted on the rotation shaft and rotates, and the second gear meshes with the first gear to rotate. A gear mounting shaft which protrudes upwardly to be mounted, a gear mounting groove into which the first and second gears are inserted, and an inlet portion formed in a predetermined space at one side where the first and second gears are engaged； A pump housing including a drain formed on the other side of the water inlet and a bubble supply pipe connecting hole formed to penetrate through one side of the drain and connected to a bubble supply pipe； It is mounted to the open upper surface of the pump housing, the inlet pipe connecting portion for connecting the inlet and the water supply pipe is supplied, and the cover having a drain pipe connection for connecting the drain pipe and the drainage portion is discharged water The present invention relates to a pump for microbubble generators having self-absorption capacity.본 발명은 자흡능력을 가지는 미세기포발생기용 펌프에 관한 것으로서, 모터의 일측에 모터케이스와 일체로 펌프하우징을 형성하되 펌프 구동이 멈추어도 항상 펌프하우징 내부는 물 충진상태를 유지하도록 함으로써 펌프구동할 때마다 물을 펌프하우징에 공급하지 않아도 작동할 수 있도록 하기 위하여 개발된 것으로；모터케이스의 상방향으로 회전축이 돌출 형성되는 모터와；상기 모터케이스와 일체로 형성되어 상면은 개방되고 저면은 막혀 있으며 저면으로 상기 모터의 회전축이 돌출 형성되고, 상기 회전축에 장착되어 회전하는 제1 기어와, 상기 제1 기어와 맞물려 회전하는 제2 기어가 장착되도록 상방향으로 돌출 형성되는 기어장착축과, 상기 제1 및 제2 기어가 삽입되는 기어장착홈과, 상기 제1 및 제2 기어가 맞물리는 일측에 일정 공간으로 형성되는 입수부와, 상기 입수부의 타측에 형성되는 배수부와, 상기
