Using this expansion tank saves water and electricity by eliminating the pulsating operation of pressure switch pumps and supplies a constant flow of water for only the quantity required. This extends the life of the pump and boiler and cuts water consumption. The internal pressurised diaphragm provides a smooth, surge-free flow.
This expansion tank is precharged at 0.9 bars (13.05 psi) but it can be charged with the special valve with a normal compressor, which allows it to be adapted to all pressure switch pumps on the market. Supplied with straight and angled 13mm flexible hose connectors and self-tapping screws for fitting.
