Diaphragm type pulse dampers use a flexible diaphragm to separate the fluid from a compressible gas or liquid, while air bag type pulse dampers use a flexible bag or bladder filled with gas or liquid to absorb the pulsations.
One of the main benefits of using Pulsation Dampers is their ability to equalize pressure fluctuations in a fluid system, resulting in low-pulsation metering. This ensures a stable flow of fluid and prevents damage to system components such as pipes, valves, and meters.

Diaphragm pulse damper reduce pressure fluctuations in fluid systems caused by equipment like pumps and compressors, helping to prevent damage to system components and maintain a steady flow of fluid.
Our company produces various types of Pulse Dampers, such as Diaphragm type, Air bag type, and Air pulse type. These dampers are commonly used in industries such as chemical, water treatment, and oil, as well as in laboratory settings. Additionally, our Pulse Dampers are suitable for use with air and various types of corrosive liquids.
Design features of diaphragm type pulse damper
The diaphragm structure separates the medium and compressed gas to ensure long-term stable operation. Only the lower housing and diaphragm come into contact with the medium, and the diaphragm, made of rubber lined PTFE processed by multi-directional rolling, has good corrosion resistance and a long service life.
Our pulsation dampers are available in different versions: diaphragm accumulators, in-line dampers, bladder dampers and accumulators

Airbag pulse damperThe airbag-type pulse damper is a device used to reduce pulsations or pressure fluctuations in a fluid-carrying pipeline. It is designed with an airbag that is filled with a specific pressure of air and placed inside an air tank. As fluid flows through the pipeline, it compresses the airbag, causing it to expand and contract. This action effectively reduces pressure surges and pulsations, providing a more stable and consistent flow. The airbag-type pulse damper is highly sensitive and can support much higher pressure, making it an ideal choice for applications where precise pressure control is required. Air pulse dampers use…- PVC Series Back Pressure ValvesAll thermoplastic diaphragm Back Pressure Valve for chemical feed systems, applies back pressure to a metering pump to prevent siphoning and eliminates varying dosage rates resulting from fluctuating downstream pressure. When the preset pressure is exceeded, the diaphragm is forced up and chemical flows through the valve to the injection point. All valves are preset for 50 psi, but are field adjustable via the adjustment screw. Installation should be as close to the injection point as possible to prevent chemical line drainage and it is most important that all chemical system equipment such as pulsation dampeners and pressure gauges are…
