Zilmet Expansion Vessels

Zilmet is Europe's largest manufacturer of expansion vessels and plate heat exchangers. Their products are known for their high quality and excellent performance.

As a company committed to research and development in order to stay at the forefront of the industry, Zilmet expansion vessels are some of the most advanced you can find. The range that we stock at Pump Sales Direct has been selected so that you can find an expansion tank that will fit with your heating system, regardless of how large, small, simple or complicated it is.

A pressure vessel is designed to act as a cushion against changes of pressure in a system. The tank contains two compartments, one containing water, the other air stored under pressure. It acts like a surge tank; when there is a rise in pressure, water can spill into the pressure vessel, reducing the risk of burst pipes.

The Zilmet Ultra Pro model range offers a huge amount of versatility. This line of products can be used in every modern installation and can be applied to any type of pump. It is for this reason that we stock such an extensive array of Ultra Pro models, as well as Zilmet’s Inox-Pro, Hydro-Pro and Cal-Pro units.

If you are unsure which type will suit your needs then you can consult the datasheet available on each product page. For more information on how Zilmet can help protect your heating system, feel free to get in touch and we can find a pressure vessel to suit your needs.
