API 682 - Plan 53C Barrier Fluid Pressurized by Piston Accumulator

Plan 53C is a dual seal solution that circulates fluid between the dual seals. It is optimal for applications where the seal chambers vary. Its purpose is to:

  • Isolate fluid from the process side
  • Better control barrier fluid pressure as seal chamber pressure fluctuates
  • Remove heat
  • Nearly eliminate process emissions
  • Allow for higher pressures compared to API 682 Plan 53A, and monitor pressure
