The universal expansion tank 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 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
