Diaphragm pulsation dampers, also known as pulsation buffers, are essential components in metering pump systems. They effectively eliminate pipeline pulsations and prevent water hammer, ensuring stable flow control and system protection. these dampers are widely used in dosing systems and industrial flow control.
Carbon steel pulsation dampers offer exceptional mechanical strength, making them ideal for high-pressure metering pump systems.
Compared to stainless steel dampers, carbon steel provides a more economical solution without compromising performance.
Our carbon steel diaphragm pulsation dampers feature a nickel-plated coating, offering excellent corrosion resistance and ensuring long-term stability in harsh environments.
Carbon steel diaphragm pulsation dampers are an essential solution for stable flow control, pressure regulation, and pulsation reduction in metering pump systems. With high durability, cost-effectiveness, and corrosion resistance, they are widely used across water treatment, power generation, and chemical industries.

"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."
