Abstract

The invention discloses a self-priming water pump with a filter device. The self-priming water pump comprises a water pump body, wherein a water inlet is formed in one side of the water pump body, and a water outlet is formed in the top of the water pump body; the filter device is arranged on one side of the water inlet and comprises a filter cover, and a sealing ring is arranged in the filter cover; a filter, a filter cup and a water outlet connecting piece are successively arranged at the bottom of the filter cover, and a buckling groove and a buckling hook are respectively arranged the bottom of the filter and the top of the filter cup and are matched with each other. As the self-priming water pump is provided with the filter cup, in the process that a worker cleans the filter, sand cannot drop out from the surface of the filter to enter an impeller again so as to damage a sealing piece, and the service life of the water pump is prolonged. The filter cup with a simple structure can effectively prevent sand from entering the impeller and protect the sealing of the water pump, and the service life of the self-priming water pump is prolonged.
