Features and Benefits

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.
