Blacoh Fluid Control Sentry XP Series pulsation dampeners are devices used in fluid systems to reduce pressure fluctuations or pulsations caused by AOD, peristaltic and metering pumps. They also eliminate water hammering and pipe vibration, thus safeguarding other equipment like filters, sensors, seals and gauges. Their simple design allows for quick installation and easy in-line maintenance. They are made of stainless steel for durability and come equipped with a BUNA-N / EPDM / PTFE / Viton bladder that separates the process fluid from the gas charge within the dampener as well as offers shock absorption.
