The Fiamma Universal A20 Expansion Tank is suitable for all caravan and motorhome pressure switch pumps making it ideal for Shurflo and Whale water pumps.
Using this expansion tank saves water and electricity by eliminating the pulsating operation of pressure switch pumps and supplies a constant flow of water for only the quantity required. This extends the life of the pump and boiler and cuts water consumption. The internal pressurised diaphragm provides a smooth, surge-free flow.
This expansion tank 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.
