  • Wear plate for a centrifugal pump
    Publication number: 20090232639
    Abstract: A wear plate for use in a centrifugal pump is structured with at least one cutting element positioned at the inner bore of the wear plate, the cutting element or elements being positioned to impact the cutting edge of the vanes of an impeller and oriented in a direction relative to the rotation of the impeller so that the wear plate cutting element or elements can capture the solids in a processed fluid and hold them in place until the solids can be cut by the impeller vane or vanes, the wear plate cutting elements further being structured to be self-sharpening.
