Hydac accumulator charging and testing units are used to charge accumulators with nitrogen or to check or to change the existing pre-charge pressure in accumulators

Safety and shut-off blocks DSV is used to isolate and discharge hydraulic accumulators

• NG = 10
• pmax = 350 bar
• simpler version of the SAF 10

Pulsation dampers welded SBO

• V = 0.075 ... 4 l
