"All our accumulators are dispatched without pre-charge. A pre-charge incurs additional cost. Contact us for more information.” 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. It happens when the pressure increases, leading to the compression of the gas. 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: Bladder Accumulators Standard No. 3.201 Bladder Accumulators Low-Pressure No. 3.202 Accumulators No. 3.000 Specifications: V = 0.5 ... 200 l p = 330 ... 1,000 bar
