Vertical GBV 750 diaphragm tank – IBO ITALY pressure tank for hydrophore systems
The vertical GBV 750 diaphragm tank is a 750 l pressure tank for hydrophore systems by IBO ITALY. It stores water under pressure and stabilizes pressure in a hydrophore system, reducing how often the pump switches on. An EPDM diaphragm inside separates the water from the compressed gas cushion.
Who it’s for
-
Hydrophore system installers – the 1" connection and EPDM diaphragm make it easier to install the tank in a hydrophore system.
-
Systems with hydrophore pumps and their own water source – the tank stabilizes pressure and reduces the number of pump start-ups during water consumption.
-
Facilities requiring a reserve of pressurized water – the 750 l capacity provides an adequate usable volume between pump cycles.
-
Technical service – the EPDM diaphragm and adjustable pre-charge pressure make it easier to start up and inspect the system.
Applications
The vertical GBV 750 diaphragm tank stores water under pressure and stabilizes pressure in a hydrophore system, reducing how often the pump switches on and wear on the system.
It is used in hydrophore systems supplied by surface or submersible pumps. The GBV 750 tank is installed vertically on the pump’s discharge side.
GBV 750 tank features – description and technical data
The tank body is made of steel coated with an exterior protective 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 match the pump’s switch-on pressure. The tank is compatible with systems with a maximum operating pressure of 10 bar and a temperature range from −10 to 100°C.

Frequently asked questions (FAQ) – vertical GBV 750 diaphragm tank
What is the vertical GBV 750 diaphragm tank used for?
The IBO ITALY GBV 750 tank stores water under pressure and stabilizes pressure in a hydrophore system. It reduces how often the pump switches on and protects it from excessive cycling.
What is the difference between the GBV tank and the horizontal GBH version?
The GBV tank is installed vertically and designed for pressure booster systems. The horizontal GBH version differs in its installation orientation and is available in capacities from 24 to 150 l. Both types have an EPDM diaphragm and operate at pressures of up to 10 bar.
What is the pre-charge pressure of the GBV 750 tank?
The factory pre-charge pressure for this model is 4 bar ±10%. For the pressure booster 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 750 diaphragm tank?
The tank is installed vertically, with a 1" connection, in a pressure booster system on the pump's discharge side. An isolation valve is recommended to facilitate servicing, and the pre-charge pressure should be checked before commissioning.
Where can I buy the GBV 750 diaphragm tank?
The manufacturer does not sell directly. The IBO ITALY GBV 750 tank is available from trading partners, plumbing wholesalers, and authorized online distributors.
What warranty does the GBV 750 diaphragm tank have?
The IBO ITALY GBV 750 diaphragm tank comes with a 36-month (3-year) manufacturer's warranty. Dambat provides warranty and post-warranty service.
