Abstract
A stainless steel sleeve is loosely disposed on a shaft portion projecting outwardly from a stuffing box bore and at least one end of the sleeve projects into the stuffing box bore and includes a seal member for establishing a sliding fluid-tight seal between the stuffing box bore and the sleeve. The sleeve is supported from the stuffing box for axial shifting relative thereto, but is keyed to the stuffing box against rotation relative thereto. A second sleeve component constructed of carbon/graphite is mounted on the shaft portion outwardly of the stainless steel sleeve and includes seal structure forming a fluid-tight seal between the shaft portion and the second sleeve. The opposing axial ends of the stainless steel and second sleeve include end faces disposed in planes normal to the center axis of the shaft portion and in sliding engagement with each other. Spring structure is operatively connected between the stuffing box and the stainless steel sleeve and yieldingly biases the latter along the shaft portion toward and into frictional engagement with the adjacent end of the second sleeve.
