A PP / UPVC / PTFE Pulsation Dampener is a device used in dosing pump systems to reduce pressure pulsations and flow fluctuations caused by positive displacement pumps. It helps ensure smooth and stable fluid flow in pipelines. ⚙️💧 🔎 What is a Pulsation Dampener? A pulsation dampener is installed on the discharge line of a dosing pump to absorb the pressure spikes (pulsations) created during the pumping cycle. Dosing pumps deliver fluid in pulses, not continuous flow. The dampener smooths these pulses to create a steady flow. 🧱 Materials Used 1️⃣ PP (Polypropylene) Good chemical resistance Lightweight Used for general chemical dosing 2️⃣ UPVC (Unplasticized Polyvinyl Chloride) High corrosion resistance Common in water treatment plants Cost-effective 3️⃣ PTFE (Polytetrafluoroethylene) Excellent chemical resistance Suitable for strong acids and solvents Used in harsh chemical environments ⚙️ Main Components Dampener body (PP / UPVC / PTFE) Internal diaphragm or bladder Gas chamber (usually nitrogen or air) Fluid inlet/outlet connection Charging valve (in some models) 🔄 Working Principle The dosing pump sends pulsating fluid flow. The pulsation dampener absorbs pressure spikes. The internal diaphragm compresses the gas chamber. The stored energy is released smoothly. ➡️ Result: Smooth, constant flow in the pipeline.
