    Abstract: A stuffing box which prevents the escape of highly pressurized, hot, solids-containing and/or toxic fluid media from the housing of a centrifugal pump has a receptacle with a flange which is sealingly secured to the housing and with a cylindrical portion spacedly surrounding that part of the pump shaft which extends from the housing. The receptacle contains a ring-shaped stop which is adjacent to the housing and surrounds the shaft, one or more deformable annular packings surrounding the shaft adjacent the stop, a reciprocable annular gland adjacent to the packings opposite the stop, and a sealing ring which engages the receptacle and the shaft and defines with the gland a plenum chamber for a sealing fluid. The pressure of sealing fluid exceeds the pressure of fluid medium in the pump housing, and the sealing fluid biases the gland against the packings so that the packings expand and sealingly engage the shaft and the internal surface of the cylindrical portion of the receptacle.
