|Wellhead stuffing box SU PK 2-73 is designed to seal the stuffing box rod of wells operated by sucker rod pumps.
Distinctive features of this design of the wellhead seal are the use of rubber-fabric cuffs with an increased operating life, the presence of a spherical pivot and an anti-blowout valve, which allows:
compensate for the misalignment of the wellhead and the gland rod hanger within the circular coordinate + – 50 mm.
prevent accidental blowout from the well in case of piston.
