Function
1. Reduce the harm of the water hammer on the system.
2. reduce the peak of the flow rate fluctuation.
3. protect the pipeline, elbow, joints from pressure fluctuations.
4. Create a good working environment for the metering pump and improve the working performance of the pump.
5. allowing the system to use smaller pipe diameters and reduce costs.
6. use with the back pressure valve can make the pressure fluctuation of the pipeline close to zero.
7. reduce the energy consumption of the system.

Operational Principle
According to Boyle’s law P1V1=P2V2, the pulsation of the pipeline is smoothed by the volume of the gas. For systems with sinusoidal curve characteristics of flow rate, when the wave peak, the volume of the air chamber becomes smaller, the Pulsation Dampener absorbs the excess flow of liquid, and during the trough, the volume of the air chamber becomes larger, and the stored liquid is released, so as to achieve the effect of smooth pulsation.

Features
It can be pre-inflated, and the effect of smooth pulsation after inflation is better than that of air-type pulsation dampers.
The gas does not come into contact with the liquid in the pipeline; the gas is not lost by dissolving into the liquid.
A limit device is provided to prevent excessive deformation of the diaphragm.
