Pressure tank Omnigena OM100H 100 L horizontal bladder tank

The Omnigena OM100H 100 L horizontal bladder tank is a compact pressure vessel designed for domestic and light commercial water systems. The tank stores pressurized water in a rubber bladder to reduce pump cycling, stabilise delivery pressure and provide a reserve volume for short periods of high demand. Its horizontal configuration and 100‑litre capacity make it suitable for installations with limited height or where proximity to the pump and service access are required.

Advantages

The horizontal bladder design minimises installation height while preserving usable water volume and pressure stability. A pre‑installed rubber diaphragm separates the water and air chamber to prevent air absorption and maintain consistent pressure behaviour. The tank’s corrosion‑resistant external finish and compact footprint facilitate mounting near pumps or on concrete floors in basements and utility rooms. Overall, the product reduces pump on/off cycles, which can extend pump life and improve energy efficiency.

Suitable for

• Domestic water supply systems with domestic pumps
• Small commercial or light industrial sites requiring pressure buffering
• Installations with limited vertical space where a horizontal tank is preferred
• Booster pump assemblies and near‑pump mounting

Key specifications

• Nominal volume: 100 litres
• Orientation: horizontal bladder (diaphragm) tank
• Function: pressurised water storage to reduce pump cycling and stabilise pressure
• Typical application: domestic and light commercial water systems
• Construction: steel shell with internal rubber bladder separating water and air
• Connection type: standard threaded connection for pump and system piping (verify compatibility during installation)

How to use

Install the tank close to the pump or pressure system on a stable, level surface in a location protected from freezing. Connect the tank to the pump discharge or system piping using the appropriate threaded fitting and ensure all joints are properly sealed. Pre‑charge the air side of the tank to the manufacturer’s recommended pressure (typically slightly below the pump cut‑in pressure) before placing the system into service; check and adjust the pre‑charge periodically to maintain correct operation. Follow local plumbing codes and the pump manufacturer’s instructions during installation and commissioning.

Usage recommendations

Periodically inspect the tank for external damage, verify pre‑charge pressure with a pressure gauge when the system is depressurised, and drain and service the connected pump according to its maintenance schedule. Avoid exposure to freezing temperatures and protect fittings from corrosion. For optimal performance match the tank pre‑charge to the pump control settings and check compatibility with system flow and pressure requirements.
