Hydac Piston Accumulators SK280
- Standard 280 bar
- Manufactured and tested to PE D 97/23/EC
- higher pressures on request
- Temperature range: -30 °C ... +80 °C
- others on request
HYDAC piston accumulators consist of:
- A cylinder with very finely machined internal surface
- End caps on the gas side and the oil side. Sealed with O-rings
- A floating steel or aluminium piston.

Advantages of the SK280 Piston Accumulator:
- Optimized production process, saving on material and manufacturing costs
- Reduced-weight series
- Reduced installation space
- Standard gas valve M28x1.5 integrated into end cap (non-refillable version possible)
- Endurance tested (function and fatigue tests)
