This pulsation dampener is designed to reduce pressure fluctuations or pulsation common in all positive displacement pump systems. It must be nitrogen pre-charged prior to installation on the discharge side of the pump. It is a replaceable bladder design constructed of 316SS with an FPM bladder for special fluid compatibility. It will prolong the life of the pump and system components by reducing pulsation to + or- 3%. [See optional NBR and EPDM versions]


• Rebuildable and rechargable.
• Optional bladder materials for liquid compatibility and 316 stainless steel construction for strength and liquid compatibility.
• Convenient rebuildable style with top access permits replacing bladder without disturbing plumbing.
• Nitrogen precharged to eliminate moisture and provide smooth bladder compression and pressure release.
• Absorbs system shocks while minimizing excessive pipe vibration, water hammering and pressure fluctuations.
