The ELBI HX2 stainless steel accumulator (drukvat) is a compact 2-litre pressure vessel engineered for domestic and light-commercial water boosting, pump systems, and water-hammer damping. Built with a fixed butyl diaphragm and robust stainless-steel shell, this vertical HX2 model delivers reliable performance in potable water systems and booster applications where corrosion resistance and sanitary construction matter.

• Capacity: 2 litre stainless-steel accumulator.
• Main connection: ½" male BSP.
• Diaphragm: fixed butyl membrane (non-replaceable on HX2 fixed-bladder models).
• Maximum pressure: 10 bar; Working pressure: 8 bar.
• Compact dimensions: approx. L 230 mm × D 146 mm; Weight ≈ 1.0 kg.

Specifications above are drawn from manufacturer listings and distributor technical notes; please verify fitment and compatibility with your pump and local plumbing standards prior to installation.

Typical uses include pump pressure stabilization, reducing pump cycling (pump hunting), acting as a small pressure buffer in booster sets, and functioning as a water-hammer arrestor in tight plumbing layouts. Its stainless construction and potable-water-compatible membrane make it suitable for domestic drinking-water booster systems and compact pressure units.

Installation tip: mount on a stable bracket or shelf close to the pump suction/pressure line, confirm pre-charge and system pressure compatibility, and follow local codes and ELBI installation guidance for safe, long-lasting operation.
