Pulsation damper, also known as pulsation buffer, is a commonly used component for eliminating pipeline pulsation. It is an accessory that must be equipped with metering pumps. The pulse damper can smooth out the pipeline pulsation and water hammer phenomenon caused by volumetric pumps such as plunger pumps and diaphragm pumps. Common styles of pulse dampers include diaphragm type, bladder type, and air type.
