The A20 pressure compensation tank ensures an even and smooth water flow by balancing pressure fluctuations in the system and preventing the pump’s pulsating operation. The integrated membrane absorbs water hammer and guarantees a constant flow at the outlet – providing greater comfort and reduced water consumption. Thanks to its black design, the A20 visually integrates perfectly into the pump and accessories series, creating a harmonious overall appearance. Compatible with all Fiamma pumps as well as with models from other manufacturers.
