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 all types of pressure switch pumps (e.g. Shurflo and Flojet)
The new expansion tank helps to eliminate 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.
