Abstract
The present disclosure relates to a water pump in which an upper casing and a lower casing are coupled to each other and an impeller is rotatably accommodated therein, in which the upper casing has an upper bulkhead formed to protrude at a position between an impeller accommodating space and a discharge channel in a radial direction, the lower casing has a lower bulkhead formed to protrude at a position between the impeller accommodating space and the discharge channel in the radial direction, and a gap (TcA) between an upper side of an outer side end of the impeller and the upper bulkhead in the radial direction is formed greater than a gap (TcB) between a lower side of the outer side end of the impeller and the lower bulkhead in the radial direction, thereby reducing a thrust generated when the impeller rotates.
