Slurry Seal Assembly And Method Thereof
Abstract: A slurry seal assembly (20) for use about a rotatable shaft (21) between a process side (54) and an atmosphere side (55) is presented. The slurry seal assembly (20) includes a sleeve (22) a rotatable seal ring (23) a stationary seal ring (24) a floating bushing seal assembly (50) and a plurality of slots (52). The sleeve (22) is disposed about and rotatable with the shaft (21). The rotatable seal ring (23) contacts and is rotatable with the sleeve (22). The stationary seal ring (24) is arranged to form a sealing interface (25) with the rotatable seal ring (23). The floating bushing seal assembly (50) is disposed about the sleeve (22) so that an inner annular surface (66) along the floating bushing seal assembly (50) is separated from an outer annular surface (67) along the sleeve (22) by a gap (65). The slots (52) are disposed along the sleeve (22) within the process side (54) adjacent to the floating bushing seal assembly (50). The slurry seal assembly (20) is applicable to devices whereby a fluid is movable between an inlet and an outlet.
