HST
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.
