Diaphragm accumulator H series

nitrogenfor mineral oilfor non-aggressive fluids

Maximum working pressure (PS): 250-210 bar Test pressure (PT): PS x 1,43 / 1,3 / 1,5 Body: made in painted carbon steel Standard nitrogen valve : ⅝” UNF (R version) Constructive methodology: exectution with caulking, without welds Working temperature (TS): from -20°C to +80°C Standard diaphragm: can be used with mineral oils and non corrosive fluids, not replaceable 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.
