Abstract
A pump features a casing assembly having a region through which high velocity fluid and solids circulate, a chamber where they do not, an aperture that allows a related-chamber to be in fluidic communication with the region, but not the circulating high velocity fluid and solids, and a corresponding aperture to allow the related-chamber to communicate with an external region outside the casing assembly; and a rupture disc received in the corresponding aperture to close the related-chamber subjects the related-chamber and the rupture disc to pressure contained within the region and to release pressure exceeding a predetermined relief pressure of the rupture disc from the related-chamber to the external region or location, and exhaust piping couple the rupture disc to provide a path for escaping vapor and solids to be directed to the external region or location where the energy can be dissipated.
