Bladder type hydro pneumatic accumulators / pulsation dampeners, made of carbon steel or stainless steel AISI 304L/316L, welded construction. The advantage of this series is the simplicity of the bladder replacement through the disassemble of the top flange.

Technical Features:

• Maximum working pressure (PS): 14 bar 
• Test Pressure (PT): PS x 1,43 / 1,3 / 1,5 
• Material: carbon steel / stainless steel Working temperature (TS): -20°C to +80°C 
• Standard bladder: can be used with mineral oils and non corrosive fluids
• Installation: 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
