Polished Rod Centralizer

POLISHED ROD CENTRALIZER

  • Prevents catastrophic blow out of stuffing box rubbers
  • Creates up to a 50% decrease in differential pressure between the flow line and stuffing box (Black Gold tested)
  • Centralizes polished rod in pumping tee
  • Prevents uneven wear and extends life of stuffing box rubbers
  • Prevents safety hazard, fines, loss of production, difficult clean-up and bad publicity
Black Gold's Polished Rod Centralizer is a two-step pollution control product designed to increase the life of the stuffing box’s rubber and mitigate the chance of catastrophic leaks.
Installed between the stuffing box and production tee, the Polished Rod Centralizer centers the polished rod in a barrel. This eliminates any misalignment and significantly reduces wear on the stuffing box’s packing. In addition, the Polished Rod Centralizer greatly reduces the amount of pressure applied onto the stuffing box from the flow-line, and further minimizes leakage through the packing.

With this combination, the Polished Rod Centralizer has proven time and time again to be the solution that makes costly stuffing box failure a thing of the past.
