Abstract
A centrifugal pump having a sealing flushing system. An annular flush ring insert having a plurality of radially spaced flush holes is provided adjacent the seal to be flushed so as to permit the seal to be flushed at a number of different places around the pump shaft and from a plurality of different radially spaced directions. The flushing fluid flows through a gland, into and through the flush ring insert, flushes (i.e. cleans and/or cools) the seal, and then flows on into the fluid being pumped.
