The capabilities of a stuffing box seal are determined not only by the unit design and operating conditions, but also depend on the proper choice of stuffing box packing. A stuffing box seal is still the most commonly used type of seal on centrifugal pump shafts operating under conditions of relatively low values of the pv -factor. The principal function of a slickline stuffing box is to seal around the wire at the upper end of the lubricator during slickline operations, in both static and dynamic conditions. where an elastomer seal such as an O ring would not be suitable. *��lvN��5���D�S}�@�xrWZm���F�jу
