摘要： 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.

摘要： A regenerative pump according to the present invention includes a rotatable impeller disposed in a housing. The impeller has a plurality of radially extending vane members spaced apart about a periphery of the impeller. Each vane member has circumferentially-facing upstream and downstream surfaces, relative to an operational direction of impeller rotation. At least one of the upstream and downstream surfaces of each vane member has a proximal portion which is inclined or curved away from the operational rotation direction, and a distal portion which is inclined or curved towards the operational rotation direction. The curved/inclined surface advantageously enhances pump efficiency.
