H

Patented execution, bladder type hydropneumatic accumulators.

Technical features

  • Maximum working pressure (PS): 250-210 bar
  • Test pressure (PT): PS x 1,43 / 1,3 / 1,5
  • Body: made in painted carbon steel
  • Standard nitrogen valve : 5⁄8” UNF
  • Constructive methodology: patented execution with caulking, without welds
  • Working temperature (TS): from -20°C to +80°C Standard bladder: can be used with mineral oils and non corrosive fluids, not replaceable
  • Installation position: horizontal / vertical (nitrogen valve upward)

Compression ratio:

  • recommended: P2/P0 = 2.5
  • maximum: P2/P0 = 4

Mechanical life: the number of cycles is inversely proportional to the increase of the compression ratio. For pulsation dampener applications, the nitrogen value must be from 60% to 80% of the working pressure also in relation with the type of pump and the working temperature.

Also available:

  • Outside epoxy painted as per standard FOX procedure or as project specification
  • Bladders in HNBR, EPDM, FPM, HYTREL
  • Connection with flange SAE 3000 – SAE 6000
  • Connection with flange ANSI B16.5 or UNI/DIN
  • Special connection on request
  • LT series for temperature up to – 40°C
  • M series rechargeable with nitrogen valve M28x1.5
  • V series not rechargeable with a fixed nitrogen preload in the factory - Version 310 bar
