Bladder accumulator HB series

for mineral oilfor non-aggressive fluidshydro-pneumatic

Maximum working pressure (PS): 350-480-690 bar Test Pressure (PT): PS x 1,43 / 1,3 / 1,5 Body: forged steel, sand and painted Standard nitrogen valve : ⅝” UNF Working temperature (TS): -20°C ÷ +80°C Standard bladder: can be used with mineral oils and non corrosive fluids Installation: 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.
