PP/UPVC/PTFE Pulsation Dampener

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.
