Pulsation dampers in hydraulic piping systems

The task of pulsation dampers consists in attenuating the pressure fluctuations in hydraulic or pneumatic  networks. This can be achieved through absorption silencers or through interference or reflection dampers.

In order to gain maximum attenuation it is not sufficient to align the damper design onto the required resonant frequency. It is also equally important to consider the dynamic response of remaining network and to place the damper at a position of maximum pressure fluctuation.
