The Hydraulic Stuffing Box is used when it is necessary to perform wireline work under well pressure. The Stuffing Box is equipped with sheave. The sheave assembly allows the wireline to be guided in its travels from the wireline unit into and through the Stuffing Box Body Assembly.
The wireline passes through the packing in the Stuffing Box Body, the packing nut is then hydraulically activated sufficiently compress the packing to minimize leakage around the wireline. A blow-out plug is situated in the lower section of the body and in the event of wire failure the plug will move upward (due to differential pressure) and seal off well pressure to the surface.
The Hydraulic Stuffing Box is available with working pressure ratings from 5,000psi to 20,000psi; for standard and sour environments.
The Hydraulic Stuffing Box may be operated hydraulically with any source capable of providing required pressure. Manual override is available in case of hydraulic failure (for Standard Type).
