Diaphragm Accumulators

The pressure fluctuations occuring in hydraulic systems can be periodical or one-off 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

QHP/HYDAC hydraulic dampers are particularly suitable for damping such pressure fluctuations.

Selecting the most suitable hydraulic damper for each system ensure that:

  • Vibrations caused by pipes, valves, couplings etc are minimised and resulting 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
  • A pump rpm and feed pressure increase is possible
  • The maintenance and servicing costs can be reduced
  • The service life of a system is increased
