Expansion tanks are used to stabilize and maintain pressure in water supply systems, as well as to reduce the pump's start/stop cycles, extending the motor's lifespan.

The diaphragms of the tanks are made of EPDM rubber.

These tanks are of high quality, thanks to the use of thicker metal sheets in their production compared to similar products on the market.

They come from the factory with a pressure of 1.7 bar. When choosing a tank, special attention should be paid to its weight - a heavier tank means a more durable tank over time.
