A Volumetric Pulsation Dampener is a device used in dosing pump systems to absorb and smooth out flow pulsations created by positive displacement pumps. It works by providing a temporary storage volume where excess fluid during pressure spikes can expand and then release smoothly. ⚙️💧 🔎 What is a Volumetric Pulsation Dampener? A volumetric pulsation dampener reduces the pressure and flow fluctuations produced by pumps such as diaphragm or plunger dosing pumps. It contains an internal gas chamber or flexible diaphragm that compresses and expands to absorb pulsations. ⚙️ Main Components Dampener body – Pressure vessel (metal or plastic) Flexible diaphragm / bladder – Separates gas and liquid Gas chamber – Usually filled with air or nitrogen Fluid connection – Inlet/outlet from pipeline Charging valve – Used to set gas pressure (in some models) 🔄 Working Principle The dosing pump produces pulsating flow. When a pressure spike occurs, some liquid enters the dampener. The gas chamber compresses, absorbing the pressure. When pressure drops, the gas expands and pushes liquid back into the pipeline. ➡️ Result: Smooth and stable fluid flow.
