... are hydropneumatic accumulators with a flexible bladder as a separation element between compressible gas cushion and operating fluid.
HYDAC bladder accumulators consist of a welded or forged pressure vessel, the accumulator bladder and the fittings for the gas- and medium-side connection.
In addition to the standard design, special designs for particular applications are possible, for example for very high discharge speeds and high pressures.
Essential parameters are:
  • Nominal volume: 0.5 ... 450 l,

  • Permissible operating pressure: up to 1,000 bar,

  • Materials for the elastomer: NBR, ECO, IIR, FKM (FPM),

  • Accumulator shell materials: carbon steel, stainless steel, aluminium, composite materials.


HYDAC bladder accumulators have the following advantages:
  • High discharge speeds,

  • No pressure difference between fluid side and gas side,

  • Compact, low-maintenance,

  • High charging and discharging frequencies.
