The Fiamma A20 universal expansion tank saves water and electricity and is suitable for use with all pressure switch pumps.

An ideal addition to AQUA 8, shurflo and flojet types of pressure switch pumps

The new expansion tank eliminates the pulsating operation of pressure switch pumps and
supplies a constant flow of water in the required quantity, this extends the life of the pump and boiler and cuts water consumption.

The internal pressurized diaphragm provides a smooth, surge-free flow.

The A20 can be dismantled for diaphragm operations
It is precharged 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.

Supplied with fixing screws and connection fittings.
