Abstract
A system for compressing seals stacks in a stuffing box including a cylindrical housing, annular seal rings, an expanding bellows assembly, and a port in open communication with a source of fluid and with the expanding bellows assembly. Pumping fluid into the port causes expansion of said bellows assembly and compression of the seal rings.
