The membrane type pulse damper is divided into upper and lower shells, separated by a composite membrane of polytetrafluoroethylene and rubber in the middle, and is the most commonly used pulse damper. The biggest advantage is that the diaphragm separates the pre filled gas from the liquid in the pipeline, making maintenance easier. Under appropriate selection and pressure conditions, it can reduce the majority of pulses. The maximum pressure resistance of the membrane type pulse damper made of UPVC material produced by our company is 1.0MPa, the maximum pressure resistance of stainless steel material is generally 2.5MPa, and the maximum pressure resistance is 5.0MPa and 10Mpa.

The main functions of the diaphragm pulse damper are:

1. Reduce the harm of water hammer to the system.

2. Reduce the peak value of flow velocity fluctuations.

3. Protect pipelines, elbows, and joints from the impact of pressure fluctuations.

4. Create a favorable working environment for metering pumps and improve their performance.

5. Allow the system to use smaller pipe diameters to reduce costs.

6. When used in conjunction with back pressure valves, it can make the pressure fluctuations in the pipeline close to zero.

7. Reduce the energy consumption of the system.
