Technical Specifications

– Maximum Working Pressure (PS): 10 bar
– Test Pressure (PT): PS x 1.43 / 1.5
– Diaphragm: NBR, HNBR, EPDM, FPM, HYTREL, Alcryn
– Standard Nitrogen Valve: ⅝” UNF
– Installation: Horizontal/Vertical (nitrogen valve facing upwards)

Compression Ratio

– Recommended:** P2/P0 = 2.5
– Maximum:** P2/P0 = 4

Mechanical Life

The number of cycles is inversely proportional to the increase in the compression ratio. For pulsation dampener applications, the nitrogen value should be 60% to 80% of the working pressure, considering the pump type and working temperature.
