Fiamma A20 Universal Expansion Tank/ accumulator tank

The universal expansion tank/ accumulator tank from FIAMMA saves water and electricity and is suitable for all pressure switch pumps.
Increased performance for half the price.

Ideal addition to AQUA 8, previous models and all other types of pressure switch pumps (for example Shurflo and Flojet)

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.


It is pre charged at 0.9 bars (13 Psi) but it can be charged with the special valve with a normal compressor so it can be adapted to all pressure switch pumps on the market.
