<p>Disclosed herein is a pump using a waste tire, capable of providing high abrasion-resistance and corrosion-resistance, and ensuring easy manufacture and maintenance, in addition to the prevention of a water hammer and rupture due to cold. In the pump of the present invention, a casing main body (110) is made of a waste tire. An inlet port unit (130) is installed at a first opening provided at a side of the waste tire, and a housing (120) is installed at a second opening provided at another side of the waste tire in such a way that an impeller (150) is set inside the casing main body (110). An outlet port unit (140) is installed at a predetermined portion of the waste tire, thus acting as an outlet port of the casing main body. A sub-vane (152) made of a waste tire is removably mounted to a main vane (151) of the impeller.</p> |
