Further Information


A hydraulic accumulator is a device used to store potential energy. The majority of accumulators produced store energy in the form of a compressible and inert gas such as Nitrogen. The energy storage (compressed gas) is then utilised to exert force against a non-compressible fluid upon entry into the accumulator. The gas and fluid are seperated by either a floating piston or an elastomeric bladder, dependent on the application.


Accumulators can have many functions, such as:
  • Energy Storage
  • Emergency Shutdown Power
  • Pulsation/Line Shock Absorption
  • Maintain Pressure
  • Dispensate Lubricants
  • Compensate Fluid Leakage
  • Cushion Shock
  • Supplement for Pumps
  • Shorten Response Time
  • Thermal Expansion/Contraction
