Pressure vessel tank Omnigena OMNI50 — 50 L horizontal bladder tank

Horizontal bladder pressure tank Omnigena OMNI50 — 50 L horizontal bladder tank is a 50-litre nominal capacity pressure vessel designed for water supply and pump systems. The tank features a molded shell with an internal replaceable bladder that separates water from the pre-charged air cushion, helping to stabilize system pressure, reduce short cycling of pumps and provide a small reserve volume of potable water for household and light commercial installations.

Advantages

The tank’s horizontal design and compact footprint make it suitable for installation in confined spaces such as basements, utility rooms or near pump units. The molded outer shell provides corrosion resistance and mechanical stability, while the replaceable internal bladder allows maintenance without replacing the entire vessel. A standard threaded connection and balanced air/water separation contribute to consistent pressure performance and longer pump service life.

Suitable for

• Domestic water supply systems with single or multiple pumps
• Booster sets and small commercial pressure installations
• Pump protection to reduce frequent on/off cycling
• Temporary reserve water storage for taps and appliances

Key specifications

• Nominal capacity: 50 litres
• Orientation: horizontal
• Internal separating element: replaceable bladder
• Shell material: molded corrosion-resistant composite/plastic
• Connection type: standard threaded water inlet/outlet suitable for common pump fittings
• Primary function: pressure stabilization and reduction of pump cycling

How to use

Install the OMNI50 horizontally on a stable, level surface close to the pump or pressure system using appropriate mounting supports. Connect the threaded inlet to the pump discharge or system pipework following piping and sealing best practices. Pre-charge the air side to the recommended pressure for the system (typically slightly below the pump cut-in pressure) before introducing water. During commissioning, check for leaks, verify the bladder integrity and adjust the pre-charge as needed to achieve desired cut-in and cut-out behaviour.

Usage recommendations

For reliable operation, verify the recommended pre-charge pressure and re-check it periodically. Replace the internal bladder if signs of failure appear (rapid loss of pre-charge, water in the air side, or reduced effective volume). Use compatible fittings and follow local installation codes. Regular inspection of connections and pressure readings helps maintain system efficiency and prolong pump life.
