Hydropneumatic membrane accumulators have a fixed charge of air/nitrogen. The energy stored through the captive air/nitrogen in the hydro-pneumatic accumulator will push the water contained inside the bladder towards the consumption points. As the water flows and the bladder is emptied, the air/nitrogen pressure will decrease, reaching the set minimum pressure, at which time the water feed current from the pumping group to the hydro-pneumatic accumulator will be re-established.

• Its task is to reduce the overpressure and underpressure waves that propagate through the pipes to permissible values.
• Replaceable membrane, suitable for drinking water or waste water (except V-160).
• Water connection with flange or thread depending on model
• Temperature [ºC]: -10 / +100
• Red epoxy paint. (except V-160 in stainless steel Aisi-304)
• Air preload: depending on model
• CE-certified according to Directive 97/23/EC
