The 4th Series – Acumuladores de Fole metálico


Alongside bladder, piston and diaphragm accumulators, the accumulator department can now offer a fourth series – metal bellows accumulators.

A metal separating element is used between the fluid and gas side of the metal bellows accumulator. This makes it virtually gas-tight.


The metal bellows accumulators have the following special features:

  • Gas tightness
  • Maintenance-free
  • Fluid resistant in temperature ranges of -65 °C to above +160 °C

and complement the proven characteristics of bladder, piston and diaphragm accumulators.

HYDAC can therefore supply all four types of accumulator and is your expert partner for all industry sectors and applications
