Product Description


Zilmet Hydro Pro Expansion Vessel offers a compact design, with the seamless diaphragm which doesn't stretch or crease. There are no bubbles or corners to trap sediment which helps to inhibit bacterial growth; Hydro Pro has international approvals allowing its use with potable water.


The Zilmet HYDRO-PRO tank leaves the factory already tested and pre-pressurised. Air and water do not mix, eliminating any possibility of “water logging” through loss of air to the system; no corrosion.

Technical Features:

Protected pre-charge valve. Durable steel tank. Deep drawn steel shell for extra strength. MIG welding process eliminates interior rough spots and sharp edges preventing damage to the diaphragm and liner. Pre-pressurised air chamber. The butyl diaphragm isolates water from the air. Exclusive internal epoxy-polyester coating. No rusting. Mild steel connection.
