Hydropneumatic bladder accumulator with stainless steel AISI316L body in welded execution. The “HTRX” series is suitable for the use with water and with the aggressive fluids used on the alimentary, chemical, pharmaceutical and petrochemical sectors.

Technical features

  • Maximum working pressure (PS): 30 / 150 bar
  • Test pressure (PT): PS x 1,43
  • Body: in AISI 316L stainless steel
  • Constructive methodology: two (draw.1) or three (draw.2) different parts welded together
  • Bladder: different type in relation to the fluid used:
  • Perbunan (NBR) -Butile -Nitrile (NBR) -Poliuretane -EPDM -Viton - Hytrel
  • Installation position: from vertical (nitrogen valve upward) to horizontal position

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 pump’s type and the working temperature.
Also available : ALLOY 20 / HASTELLOY body
