The Lowara 24 litre horizontal pressure vessel (UK1100002498) is a 24 litre diaphragm vessel rated to 10 bar, for horizontal mounting. It stores water under pressure for water booster sets, heating pressurisation units and fill sets, at temperatures up to 70°C.

A replaceable WRAS-approved butyl diaphragm inside a carbon steel shell keeps the stored water away from the steel, so the vessel is suitable for drinking water. The diaphragm is fixed at the top and bottom so it cannot bend or rub against the shell, and the 1″ G connection is on a stainless steel flange.

FAQs

Can it be used for drinking water?

Yes — the butyl diaphragm is WRAS approved and keeps the stored water away from the steel shell.

Do I need to adjust the pre-charge?

Usually — set it to suit your system with the vessel isolated and empty of water, before filling. For booster sets this is normally just below the pump start pressure.

How should it be installed?

Fit an isolating valve and a drain cock on the vessel connection so it can be isolated, drained and checked.

What is the maximum temperature?

Up to 70°C. For hotter systems ask us about a suitable vessel.

What is a pressure vessel used for in a pumping system?

A pressure vessel stores water under pressure, helping maintain supply and reduce unnecessary pump starts.

What is the difference between an accumulator and an expansion vessel?

Accumulators provide pressurised water storage, while expansion vessels accommodate volume changes caused by temperature; product suitability depends on system design.
