Bladder accumulator used to store pressure energy
The HYDAC SB330-4A1/112U-330A is a high-performance 4-liter standard bladder accumulator used to store pressure energy, absorb system shocks, and compensate for volume changes in hydraulic circuits. It operates at pressures up to 330 bar (5,000 psi) and uses an elastic bladder to separate system fluid from compressed nitrogen gas
