Amortecedores hidraulicos


Mode of operation The pressure fluctuations occurring in hydraulic systems can be cyclical or oneoff problems due to:

  • flow rate fluctuations from displacement pumps
  • actuation of shut-off and control valves with short opening and closing times
  • switching pumps on and off
  • sudden linking of spaces with different pressure levels.

HYDAC hydraulic dampers are particularly suitable for damping such pressure fluctuations. Selecting the most suitable hydraulic damper for each system ensures that

  • vibrations caused by pipes, valves, couplings etc are minimised and subsequent pipe and valve damage is prevented
  • measuring instruments are protected and their performance is no longer impaired
  • the noise level in hydraulic systems is reduced
  • the performance of machine tools is improved
  • interconnection of several pumps in one line is possible
  • an increase in pump rpm and feed pressure is possible
  • the maintenance and servicing costs can be reduced
  • the service life of the system is increased.

The HYDAC pulsation damper

  • prevents pipe breaks caused by material fatigue, pipe oscillations and irregular flow rates,
  • protects valves, control devices and other instruments,
  • improves noise level damping.


The pulsation damper is particularly suitable for:

hydraulic systems, displacement pumps of all types, sensitive measurement and control instruments and manifolds in process circuits in the chemical industry.
