Diaphragm type hydropneumatic accumulators, threaded reparable.

Technical features

  • Maximum working pressure (PS): 300 bar
  • Test pressure (PT): PS x 1,43 / 1,3 / 1,5
  • Body: made in painted carbon steel
  • Standard nitrogen valve : ⅝” UNF
  • Working temperature (TS): -20°C ÷ +80°C
  • Standard diaphragm: can be used with mineral oils and non corrosive fluids
  • Installation position: horizontal / vertical (nitrogen valve upward)

Compression ratio:

  • recommended: P2/P0 = 2.5
  • maximum: P2/P0 = 6

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.
