The N53C piston accumulator from Flowserve provides optimal lubrication for dual pressurized mechanical seals to promote long seal life and equipment reliability across a broad range of applications. It’s designed to be easy to install, simple to operate, and requires minimal maintenance.

Features

• 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.
