Abstract
The present invention relates to an impeller containment system for containing the burst of an impeller or the burst of impeller fragments from an impeller hub. The containment system utilizes a catcher extending from a shroud plate adjacent the impeller, which engages with a snagger formed as a unitary part of the impeller. The catcher and snagger cooperate to restrain a burst impeller or impeller fragments to their shortest radial distance from their point of burst. The system also includes a shroud which circumferentially surrounds the impeller and a diffuser, which circumferentially surrounds the radial tip portions of the impeller.
