Fiamma A20 Expansion Tank

The Fiamma A20 expansion tank eliminates the pulsating operation of pressure switch pumps and supplies a constant flow of water in the required quantity. It extends life of the pump and boiler and cuts water consumption. The internal pressurized diaphragm provides a smooth, surge-free flow of water. Ideal addition to a Fiamma Aqua 8, previous models and all other types of pressure switch pumps (including Shurflo and Flojet). 

The A20 can still be dismantled for diaphragm repair and checks. It is pre-charged at 0.9 bars (13psi) but it can be charged with the special valve with a normal compressor so it can be adapted to all pressure switch pumps.
