ABSTRACT:
Packing for a stuffing box for sealing a movable shaft including a sealing ring which is used together with a non-sealing compensator ring. The sealing ring includes the annular shaft sealing lip extending from said ring body along the shaft for contacting and sealing the shaft and a stuffing box sealing lip for contacting and sealing the stuffing box. The compensating ring includes a tapered annular protrusion having wedge faces for contacting and urging the shaft sealing lip toward the shaft and contacting and urging the stuffing box sealing lip towards the stuffing box when an axially-directed force is applied to the packing. The compensator ring is adjustable in diametrical dimensions so that contact is maintained between the wedge faces and the sealing lips and an effective seal is provided even if wear occurs on the sealing ring adjacent to the movable shaft.
