The function of a pulsation dampener is to stabilize the variable and oscillating flow or hydraulic shock (sometimes referred to as acceleration head) generated in a hydraulic circuit in each cycle by volumetric piston or membrane pumps such as dosing or metering pumps. The main characteristic of these pumps being to deliver a constant volume of liquid in every cycle independently of the circuit resistance or pressure.

as possible.

Correct sizing & installation of a pulsation damper can reduce the nb (nominal bore) of the discharge pipework from a chemical dosing system and generally it is more cost effective to install a pulsation damper and have smaller discharge pipework.
