Vertical GBV 500 diaphragm tank – IBO ITALY pressure tank for booster systems
The vertical GBV 500 diaphragm tank is a 500 l pressure tank for booster systems, manufactured by IBO ITALY. It stores pressurized water and stabilizes pressure in the booster system, reducing how often the pump switches on. An EPDM diaphragm inside separates the water from the compressed gas cushion.
Who it’s for
-
Booster system installers – the 1¼" connection and EPDM diaphragm make it easier to install the tank in a booster system.
-
Systems with booster pumps and their own water supply – the tank stabilizes pressure and reduces the number of pump cycles during water draw-off.
-
Facilities requiring a reserve of pressurized water – the 500 l capacity provides a suitable usable volume between successive pump cycles.
-
Technical servicing – the EPDM diaphragm and adjustable pre-charge pressure make it easier to commission and inspect the system.
Applications
The vertical GBV 500 pressure tank stores pressurized water and stabilizes pressure in the pressure system, reducing how often the pump switches on and minimizing wear on the system.
It is used in pressure systems supplied by surface or submersible pumps. The GBV 500 tank is installed vertically on the pump’s discharge side.
GBV 500 tank features – description and technical specifications
The tank body is made of steel coated with a protective exterior paint that increases corrosion resistance. Inside is an EPDM rubber diaphragm that separates the water from the compressed gas cushion and limits its contact with the inside of the tank body. This design keeps a reserve of pressurized water and stabilizes system operation.
The factory pre-charge pressure for this model is 4 bar ±10% and should be adjusted to the pump’s cut-in pressure. The tank is compatible with systems with a maximum operating pressure of 10 bar and a temperature range of −10 to 100°C.

Frequently asked questions (FAQ) – vertical GBV 500 pressure tank
What is the vertical GBV 500 pressure tank used for?
The IBO ITALY GBV 500 tank stores pressurized water and stabilizes pressure in the pressure system. It reduces how often the pump switches on and protects it from cycling too frequently.
How does the GBV tank differ from the GBH version (horizontal)?
The GBV tank is installed vertically and is designed for pressure systems. The GBH version (horizontal) differs in its installation orientation – GBH is available in horizontal versions with capacities from 24 to 150 l. Both types have an EPDM diaphragm and operate at up to 10 bar.
What is the pre-charge pressure of the GBV 500 tank?
The factory pre-charge pressure for this model is 4 bar ±10%. For the pressure system to operate correctly, adjust the pre-charge pressure to just below the pump’s cut-in pressure.
How do I install the vertical GBV 500 pressure tank?
Install the tank vertically, with a 1¼" connection, in the pressure system on the pump’s discharge side. An isolation valve is recommended to allow servicing, and the pre-charge pressure should be checked before startup.
Where can I buy the GBV 500 pressure tank?
The manufacturer does not sell directly. The GBV 500 IBO ITALY tank is available from commercial partners, plumbing wholesalers, and authorized online distributors.
What warranty does the GBV 500 diaphragm pressure tank have?
The IBO ITALY GBV 500 diaphragm pressure tank comes with a 36-month (3-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
