The Fiamma universal A20 Expansion Tank saves water and electricity and is suitable for all caravan and motorhome pressure switch pumps. Ideal addition to AQUA 8 water pump, previous models and all other types of pressure switch pumps including Shurflo and Whale.

The new expansion tank eliminates the pulsating operation of pressure switch pumps and supplies a constant flow of water in the required quantity. It extends the life of the pump and boiler and cuts water consumption. The internal pressurised diaphragm provides a smooth, surge-free flow.

The Fiamma A20 expansion Tank can be dismantled for diaphragm operations. It is precharged at 0.9 bars (13.05 psi) but it can be charged with the special valve with a normal compressor, which allows it to be adapted to all pressure switch pumps on the market. Supplied with straight and angled 13mm flexible hose connectors and self-tapping screws for fitting.
