Vertical GBV 300 diaphragm tank – IBO ITALY pressure tank for water supply systems
The vertical GBV 300 diaphragm tank is a 300 L pressure tank for water supply systems by IBO ITALY. It stores pressurized water 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.
For whom
-
Pressure booster system installers – the 1" connection and EPDM diaphragm make it easier to install the tank in a pressure booster system.
-
Systems with pressure booster pumps and their own water source – the tank stabilizes pressure and reduces the number of pump starts during water draw-off.
-
Facilities requiring a reserve of pressurized water – the 300 l capacity provides an adequate usable volume between pump starts.
-
Technical service – the EPDM diaphragm and adjustable pre-charge pressure make system commissioning and inspections easier.
Applications
The vertical GBV 300 diaphragm tank stores pressurized water and stabilizes pressure in a pressure booster system, reducing pump cycling and system wear.
It is used in pressure booster systems supplied by surface or submersible pumps. The GBV 300 tank is installed vertically on the pump’s discharge side.
GBV 300 tank features – description and technical specifications
The tank body is made of steel coated with an exterior protective paint 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 stores a reserve of pressurized water and stabilizes system operation.
The factory pre-charge pressure for this model is 3 bar ±10% and should be adjusted to match 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 300 diaphragm tank
What is the vertical GBV 300 diaphragm tank used for?
The IBO ITALY GBV 300 tank stores pressurized water and stabilizes pressure in a pressure booster system. It reduces how often the pump starts and protects it from excessive cycling.
How does the GBV tank differ from the GBH version (horizontal)?
The GBV tank is installed vertically and is designed for pressure booster systems. The GBH version (horizontal) differs in its mounting 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 300 tank?
The factory pre-charge pressure for this model is 3 bar ±10%. For the pressure-boosting system to work properly, adjust the pre-charge pressure to a little below the pump switch-on pressure.
How do I install the vertical GBV 300 diaphragm tank?
The tank is installed vertically, with a 1" connection, in a pressure-boosting system on the pump’s discharge side. An isolation valve is recommended for servicing, and the pre-charge pressure should be checked before commissioning.
Where can I buy the GBV 300 diaphragm tank?
The manufacturer does not sell directly. The IBO ITALY GBV 300 tank is available from retail partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the GBV 300 diaphragm tank?
The IBO ITALY GBV 300 diaphragm tank comes with a 36-month (3-year) manufacturer’s warranty. Warranty and post-warranty service are provided by Dambat.
