Technical features

  • Maximum working pressure (PS): 50-450 bar 
  • Test pressure (PT): PS x 1,43 / 1,3 / 1,5 
  • Body: in AISI 316L stainless steel
  • Bladder: NBR, HNBR, EPDM, FPM, HYTREL, Butyl, Polyurethane
  • 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
