Grundfos - GT-H-18 Vertical Cold Water Diaphragm Tank - 10 Bar. - 18 Ltr

The tank is a steel pressure tank made of a virgin propylene liner. The tanks have a non-replaceable FDA-approved high-grade butyl diaphragm, which is pre-charged with compressed nitrogen (1.9 bar).

To ensure long-lasting durability, the diaphragm and liner are both reinforced in specific wear areas. All internal parts, including the air valve, are rounded to prevent piercing of the diaphragm in extreme conditions. The water connection uniquely provides a dual water and air seal ensuring a completely leakage-free pressure tank. Combined with booster and irrigation systems as well as thermal expansion and hydraulic hammer arrestors, the tank is appropriate for drinking-water and grey-water applications. It provides optimised comfort and a patented stainless-steel water connection. The tank also features:
