<p>Disclosed are a drainage pump system and a drainage system using the same. According to the present invention, the drainage pump system and the drainage system using the same include a passage through which fluid is passed formed inside a free end portion of a blade facing a center of an impeller, thereby discharging the fluid even without impeller rotation. Also, a plurality of blades are radially disposed on the same circumference with respect to the center of a rotary member of the impeller to form a blade group, and a plurality of blade groups are formed in the longitudinal direction of the rotary member in predetermined intervals, thereby maximally preventing foreign substance from being caught in the blades if the lengths of the blades facing the longitudinal direction of the rotary member are appropriately adjusted. In addition, the drainage system is completed by digging an outer portion of a storm sewer, installing the drainage pump system in the storm sewer, and installing a tank in such a way that the tank covers the drainage pump system, such that the drainage system is easily and conveniently installed.</p> |
