Pressure Tank Omnigena OM080H 80 L Horizontal Diaphragm

Omnigena OM080H is a horizontal diaphragm pressure tank with an 80-litre capacity designed for water supply and booster systems. The vessel separates water from the air volume with an internal elastomer diaphragm, providing a pressurised buffer that reduces pump cycling, stabilises system pressure and supplies reserve water for short demand peaks. The horizontal layout makes the tank suitable for installation in compact technical rooms, basements or near pumps where floor space and height are limited.

Advantages

The diaphragm design prevents waterlogging and maintains a consistent charge of compressed air, improving pump longevity and ensuring smoother pressure delivery. The 80-litre working volume offers measurable buffering for domestic water systems and small commercial booster setups. Construction materials and a welded steel shell with protective coating deliver mechanical strength and corrosion resistance appropriate for standard potable water and irrigation applications.

Suitable for

• Domestic water supply systems and household booster pumps
• Garden irrigation and lawn watering circuits
• Small commercial installations requiring pressure buffering
• Hydraulic separation near pump units in basements or technical rooms

Key specifications

• Volume: 80 litres gross capacity
• Type: Horizontal diaphragm (membrane-separated) pressure tank
• Primary function: Pressure stabilisation and pump cycling reduction
• Typical applications: Domestic water systems, irrigation, small boosters
• Installation orientation: Horizontal

How to use

Install the tank in accordance with local plumbing and building codes, positioning it close to the pump and on a stable, level surface. Connect the pressure tank to the pump or system using appropriate fittings and ensure the diaphragm is intact before pressurising. Pre-charge the air side to the recommended pressure for the pump control settings (usually slightly below the pump cut-in pressure) using a suitable air valve and gauge. After installation and pre-charge, run the pump to check for correct pressure stabilisation, leaks and proper cycling behaviour.

Usage recommendations

Verify pre-charge pressure periodically and adjust when system pressure settings change. Protect the tank from freezing and direct sunlight; inspect external coating and connections annually and drain the tank before long periods out of service.
