Gas Filled Bladder Type Pulsation Dampener
Description
A Gas-Filled Bladder Type Pulsation Dampener is a specialized device used with dosing pumps to smooth out pulsations in the flow and stabilize pressure, ensuring accurate and safe chemical injection. It is widely used in water treatment, RO plants, chemical processing, and industrial piping systems. ⚙️💧
🔎 What is a Gas-Filled Bladder Type Pulsation Dampener?
This type of pulsation dampener contains a flexible bladder inside a pressure vessel, which is pre-charged with gas (usually nitrogen).
The bladder separates the liquid from the gas.
When the pump produces a pressure spike, the liquid compresses the bladder slightly, absorbing the energy.
When the pressure drops, the gas pushes the liquid back into the pipeline, smoothing the flow.
⚙️ Main Components
Pressure vessel – Made of stainless steel, PVC, PP, or other materials
Bladder – Flexible, chemical-resistant rubber or elastomer
Gas chamber – Pre-charged with nitrogen or air
Fluid inlet/outlet connections – To connect to dosing pump or pipeline
Gas charging valve – For adjusting gas pressure
Mounting bracket – Optional, for secure installation
🔄 Working Principle
The dosing pump sends pulsating flow into the pipeline.
The liquid enters the bladder dampener.
The bladder compresses, absorbing pressure peaks.
During low-pressure periods, the gas expands, pushing the liquid back.
➡️ Result: Smooth, continuous flow with reduced pulsation.
