The diaphragm expansion tanks with replaceable diaphragms are perfectly suited for pressure boosting in accordance with the German Drinking Water Ordinance (TrinkwV 2001). The tanks keep the pressure in the water piping network constant and prevent the pumps from being activated at a low flow rate.
