Bladder accumulators are a very versatile and cost effective option for numerous types of hydraulic systems involving energy storage, shock absorption, pulsation dampening, leakage loss compensation and volume compensation. They are a first choice for a great variety of general applications and have the widest range of standard sizes and model options. Bladder accumulators also have very quick shock response characteristics in sizes much larger than diaphragm accumulators.

Mounting Type

N/A HYDAC bladder accumulators can be installed in any orientation depending upon the application. When installing vertically or at an angle, the fluid port must be at the bottom. On certain applications listed below, specific positions are preferable:

  • Energy Storage:
    • vertical
  • Pulsation Dampening:
    • any position from vertical to horizontal
  • Maintaining Constant Pressure:
    • any position from vertical to horizontal
  • Volume Compensation:
    • any position from vertical to horizontal
Caution: Mounting a HYDAC bladder accumulator horizontally or at an angle will decrease the amount of usable volume available.
