    Abstract: The present invention relates to a water pump including a lower casing in which a rotor accommodating part is formed to protrude downwardly and a lower bearing mounting part is formed at a lower end of an inner portion; an upper casing in which an inlet part introducing a fluid and an outlet part discharging the fluid are formed and an upper bearing mounting part is formed to extend from a lower end of the inlet part toward the impeller accommodating space; an impeller rotatably provided in the impeller accommodating space; and a rotor provided in the rotor accommodating space of the lower casing and coupled to the impeller. A fluid may smoothly flow toward an introduction side of the impeller, and thus, a pressure drop of the fluid and an unstable flow of the fluid may be prevented to improve performance.
