  • A spring-energized piston maintains a minimum pressure to the dual mechanical seal when the equipment is idle.
  • When the equipment starts and pressure builds in the seal chamber, a reference line from the seal chamber enables the N53C piston accumulator to boost the pressure to the dual mechanical seal and establish the required pressure differential.
  • The N53C piston accumulator will always maintain a positive pressure differential for proper operation of the dual mechanical seal.
