The HPD series by Hydroll is a patented range of double hydropneumatic piston accumulators.  The design of HPD double action pistons allows for the suspension of two movements by one accumulator.  The HPD double piston accumulator has a fluid connection in both end flanges and the gas is contained between two pistons within the one unit.

Hydropneumatic Piston Accumulators (HDC) - Double Chamber

  • 80-125 mm  ID
  • 250 bar max working pressures
  • 2 x 1 - 2 x 3,5 L volume
  • Proven, robust design
  • Space saving structure combining two accumulators into one
  • Example applications: axle suspensions

Hydroll's double chamber structure enables smooth suspension for variable loads.  The HDC10 is an accumulator solution designed for axle suspension.  A double gas chamber with a pre-charged pressure difference is the key to smooth suspension for variable payloads.  The HDC10 is based on the proven design and compoenents from the HPS series.
