Product Description


The usable capacity of these membrane pressure tanks is better to that of a normal tank. Less footprint at equal water yield, the minimum pump starts and saving in energy consumption. The wide range (vertical and horizontal) makes Zilmet pressure tanks suitable for many applications. The tank is supplied already tested and certified by our factory according to the European Directive 97/23/EC. Maximum durability of the membrane is assured as the membrane cannot bend or rub against the plate, as it is fixed at both ends of the tank. Made in Italy .

WorkingWhen the pump starts, water enters the membrane tank as system pressure passes the pressure pre-charge using the available capacity of the tank (only useable water is stored). When the pressure in the chamber reaches the maximum system pressure, the pump stops working and the tank is filled to its maximum capacity. The pressure in the air side of the tank will push water into the system when there is a further requirement. The ULTRA INOX-PRO tank does not get logged with water and delivers all water possible, minimum pump starts are assured, saving energy and increasing the pump life.
