Stuffing Box Detail information
The stuffing box is an essential component in wellheads that serves
as a dynamic sealing device, creating a seal within the annular
space between the tubing pipe and the polished rod.
The Double Packed Stuffing Box (DPSB) is a specially designed
version intended for pumping units, and it boasts several notable
characteristics:
1. It features a unique misaligning capability, which reduces the
need for precise alignment with the pumping unit, providing
flexibility during installation.
2. The primary packing can be easily changed without interrupting
operations by tightening compression bolts, allowing for efficient
maintenance.
3. Equipped with cone packing, the DPSB ensures reliable and
effective sealing, minimizing the risk of leaks.
4. The Lub Upper Gland (LUG) is equipped with a grease zerk,
facilitating the lubrication of the polished rod for improved
performance and longevity.
5. Optional components such as the Oil Reservoir Gland (ORG) and
Anti-Pollution Adapter (APA) are available to meet specific
requirements.
6. The LUG is designed with two heavy hex nuts on each bolt,
providing outstanding support of up to 20,000 lbs. during well
servicing operations, ensuring safety and stability.
7. Upon special order, a flanged bottom connection can be
accommodated, catering to unique installation needs.
8. Renowned for its reliability and versatility, the DPSB is widely
recognized as the most widely-used stuffing box in the industry,
demonstrating its trusted performance and popularity.
