Pulsation dampeners are commonly used in metering (dosing) pump piping systems to reduce pulsation and improve the overall performance and longevity of the system. They are typically categorized into three main types: air chamber type, diaphragm type, and bladder type.

Diaphragm pulsation dampers, also known as pulsation dampeners or pulsation buffers which are commonly used components in metering pump systems to eliminate pipeline pulsation and water hammer. It is an essential accessory for metering pumps.

The PVC diaphragm pulsation damper can effectively reduce or eliminate water hammer in the system,protect the system from impact, reduce the peak value of flow rate fluctuations, ensure the correct display of the pump outlet pressure gauge, reduce the impact of pressure fluctuations on pipelines, elbows, and joints, and extend the service life.

PVC material has good corrosion resistance and mechanical strength. Compared with diaphragm pulsation dampers made of other materials, PVC pulsation dampeners are cheaper and allow the system to use smaller diameter pipes during installation, reducing installation and maintenance costs. It is an essential and preferred accessory for daily chemical dosing systems and fluid control systems.
