CONSTITUTION: A pump for easily discharging foreign materials comprises a main body(10), an impeller hub(20), an impeller(30), a wearing(40), fixing bolts(50), nuts(60), nut grooves, and springs(80). A suction port is formed in one side of the main body, and an exhaust port is formed in the other side. The impeller hub is arranged inside the main body and is rotated. The impeller is vertically positioned in the outer surface of the impeller hub. The wearing is formed on the inner surface of the main body and is divided at uniform intervals. The fixing bolts fix the wearing. The nuts are coupled to the inner ends of the fixing bolts. The nut grooves are formed on the outer surface of the wearing. The springs are formed between the inner surface of the main body and the outer surface of the wearing.
