Patented execution, bladder type hydropneumatic accumulators.

Technical features

• 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 : 5⁄8” UNF
• Constructive methodology: patented execution with caulking, without welds
• Working temperature (TS): from -20°C to +80°C Standard bladder: can be used with mineral oils and non corrosive fluids, not replaceable
• Installation position: 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.

Also available:

• Outside epoxy painted as per standard FOX procedure or as project specification
• Bladders in HNBR, EPDM, FPM, HYTREL
• Connection with flange SAE 3000 – SAE 6000
• Connection with flange ANSI B16.5 or UNI/DIN
• Special connection on request
• LT series for temperature up to – 40°C
• M series rechargeable with nitrogen valve M28x1.5
• V series not rechargeable with a fixed nitrogen preload in the factory - Version 310 bar
