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.
