PURPOSE: A self-priming pump for generating fine bubbles is provided to prevent self-priming performance of a pump because high pressure air from a pumping unit discharges through an exhaust valve in spite of blockage of water outlet filter. CONSTITUTION: A self-priming pump(1) for generating fine bubbles comprises a water inlet unit(10), a pumping unit(20), an air suction unit(30), a water outlet unit(40), and a driving unit(50). One end of the water inlet unit is connected to water supply source and the other end is connected to a body(3). The pumping unit sucks water of the water supply source into the body through the water inlet unit. The air suction unit is connected to an outlet(11) of the water inlet unit of the body. The air suction unit sucks the external air by suction force of the pumping unit generating in the driving unit. The water outlet unit discharges the water and air, sucked and mixed into the body by the pumping unit, to a storage tank. |
