Horizontal GBH 150 diaphragm tank – IBO ITALY pressure tank for pressure booster systems
The horizontal GBH 150 diaphragm tank is a 150 l pressure tank for pressure booster systems, made by IBO ITALY. It stores water under pressure and stabilizes pressure in the system, reducing how often the pump switches on. An EPDM diaphragm inside separates the water from the compressed gas cushion.
Who it’s for
-
Pressure tank system installers – the 1" connection and EPDM diaphragm make it easier to install the tank in a pressure tank system.
-
Systems with pressure booster pumps and a private water source – the tank stabilizes pressure and reduces the number of pump cycles while water is being drawn.
-
Facilities requiring a pressurized water reserve – the 150 l capacity provides an adequate usable volume between pump cycles.
-
Technical service – the EPDM diaphragm and adjustable pre-charge pressure make system commissioning and inspections easier.
Applications
The horizontal GBH 150 diaphragm tank stores water under pressure and stabilizes pressure in the pressure tank system, reducing how often the pump switches on and minimizing system wear.
It is used in pressure tank systems supplied by surface or submersible pumps. The GBH 150 tank is installed horizontally on the pump discharge side.
GBH 150 tank features – description and technical specifications
The tank body is made of steel coated with a protective exterior finish that increases corrosion resistance. Inside, an EPDM rubber diaphragm separates the water from the compressed gas cushion and limits its contact with the inside of the tank body. This design maintains a pressurized water reserve and stabilizes system operation.
The factory pre-charge pressure for this model is 3 bar ±10% and should be adjusted to match the pump cut-in pressure. The tank is suitable for systems with a maximum operating pressure of 10 bar and a temperature range of −10 to 100°C.

Frequently asked questions (FAQ) – horizontal GBH 150 diaphragm tank
What is the horizontal GBH 150 diaphragm tank used for?
The IBO ITALY GBH 150 tank stores water under pressure and stabilizes pressure in a pressure booster system. It reduces how often the pump switches on and protects it from cycling too frequently.
What is the difference between the GBH tank and the GBV version (vertical)?
The GBH tank is installed horizontally and is designed for pressure booster systems. The GBV version (vertical) differs in its installation orientation – GBV is available in vertical models with capacities from 50 to 2000 L. Both types have an EPDM diaphragm and operate at up to 10 bar.
What is the pre-charge pressure of the GBH 150 tank?
The factory pre-charge pressure for this model is 3 bar ±10%. For the pressure booster system to work properly, adjust the pre-charge pressure to slightly below the pump's cut-in pressure.
How do I install the horizontal GBH 150 diaphragm tank?
The tank is installed horizontally, with a 1" connection, on the pump's discharge side in a pressure booster system. An isolation valve is recommended to facilitate servicing, and the pre-charge pressure should be checked before startup.
Where can I buy the GBH 150 diaphragm tank?
The manufacturer does not sell directly. The IBO ITALY GBH 150 tank is available from commercial partners, plumbing wholesalers and authorized online distributors.
What warranty does the GBH 150 diaphragm tank have?
The IBO ITALY GBH 150 diaphragm tank comes with a 36-month (3-year) manufacturer's warranty. Dambat provides warranty and post-warranty service.
