Bladder Accumulators – High Pressure

BladderAccumulator_HighPressure

Fluids are practically incompressible and cannot, therefore, store pressure energy. So, the utilisation of compressibility of a gas (nitrogen) in hydraulic accumulators is for storing fluids. That’s why HYDAC bases its piston accumulators on this principle.

Indeed, a bladder accumulator consists of a fluid section and a gas section with the bladder acting as the gas-proof screen. The connection of the fluid around the bladder to the hydraulic circuit results on the bladder accumulator drawing in the fluid when the pressure increases and compression of the gas happens. When the pressure drops, the compressed gas expands and forces the stored fluid into the circuit.

HYDAC bladder accumulators can be used in a wide variety of applications and are also available in different pressure ranges, see catalog sections:
