A diaphragm pulsation damper, also known as a pulsation buffer, is a commonly used component in metering pump systems to eliminate pipeline pulsation and water hammer. It is an essential accessory for metering pumps.
The stainless steel diaphragm pulsation damper features a corrosion-resistant diaphragm design that effectively isolates the precharged gas from the liquid in the pipeline, facilitating maintenance while ensuring stable system operation. Its robust structure can withstand pressures of up to 10 MPa or larger, making it suitable for high-pressure environments.
The stainless steel diaphragm pulsation damper significantly reduces the impact of water hammer on the system, lowers the peak fluctuations in flow rate, and protects pipes, elbows, joints, and other components from pressure fluctuations. At the same time, it creates a favorable working environment for the metering pump, improving pump performance and reducing energy consumption.
Stainless steel material offers excellent corrosion resistance and mechanical strength, ensuring the damper's long-term reliability under harsh conditions and extending its service life.
Our stainless steel diaphragm pulsation dampers are widely used in flow control systems and dosing systems across various industries, including water treatment, environmental protection, power generation, chemical processing, reverse osmosis, and papermaking.

"The diaphragm pulsation damper adopts the design with upper shell,lower shell,and they are separated by a diaphragm in the middle,it is the most commonly used pulsation dampener. The biggest advantage is that the diaphragm separates the pre-filled gas from the liquid in the pipeline, which is convenient for maintenance. Under appropriate selection and pressure conditions, it can eliminate more than 90% of the pulses.
Capacity selection method: Multiplying the volume of each stroke (milliliters) by 10 the minimum volume that can reduce pulses by 90%."
Design features
*The diaphragm structure separates the medium and compressed gas to ensure long-term stable operation.
*Only the lower housing and diaphragm contact with the medium, and the diaphragm is made of rubber lined PTFE which processed by multi-directional rolling ,has good corrosion resistance and a long service life.
*support small diameter pipes’ installation to reduce costs. When used in conjunction with a back pressure valve, the pressure wave in the pipeline can be reduced to near-zero."
