ABSTRACT:
In order to reduce noise generated in a westco pump when fluid hits a finishing end of a pump channel, finishing ends of grooves formed in a side wall of a casing body and a casing cover to form a pump channel are shifted by an amount equal to 1/2 of the pitch of blade elements in relation to the rotating direction of an impeller. As a result, the timings the fluid under high pressure hits the finishing ends of the grooves are staggered, thus decreasing the collision sound.
