SK 280

HYDAC piston accumulators with working pressures up to 280 bar are lightweight and cost-effective!

Fluids are practically incompressible and cannot therefore store pressure energy. The compressibility of a gas is utilised in hydro-pneumatic accumulators for storing fluids. HYDAC piston accumulators are based on this principle, using nitrogen as the compressible medium.

  • The piston accumulator consists of a fluid section and a gas section with the piston acting as a gas-proof screen
  • The gas section is pre-charged with nitrogen
  • The fluid section is connected to the hydraulic circuit so that the piston accumulator draws in fluid when pressure increases and the gas is compressed
  • When the pressure drops, the compressed gas expands and forces the stored fluid back into the circuit

HYDAC piston accumulators can be used in a wide variety of applications and are also available in different pressure grades.

Advantages of the SK 280:

  • Optimised production process, saving on material and manufacturing costs
  • Reduced-weight series
  • Reduced installation space
  • Standard gas valve
