When quality comes first


potable water, pumps and booster sets


ULTRA-PRO is suitable for any modern installation and can be applied to any type of irrigation pump, centrifugal pump and booster sets.

The food grade membrane is replaceable. The membrane pressure tank's real volume is superior than that of a normal tank, therefore, it has a smaller footprint at equal water yield, minimum pump starts and is energy saving. The wide range available, the vertical and horizontal version, the galvanised and stainless steel connection flange makes Zilmet pressure tanks suitable for any application. The tank is factory tested and certified according to EU directive 97/23/EC. Maximum duration of the membrane is assured as the membrane itself cannot bend or rub against the plate as it is fixed above to the connection and below to the flange.

The tank's lifetime is practically unlimited as the membrane can be replaced.
