Description
GBH FIX 100 Diaphragm Tank – IPRO Horizontal Tank
The IPRO GBH FIX 100 diaphragm vessel is a horizontal membrane tank for water supply and pressure-boosting systems. Inside the steel body is a non-replaceable, certified butyl membrane that separates the water from the air cushion, stabilizes system pressure, and reduces the frequency of pump starts.
Who is it for?
- Homeowners with their own water source – the IPRO diaphragm vessel maintains stable pressure at the taps and reduces the number of pump starts during everyday use.
- Water supply system installers – the horizontal design with a base and plastic feet makes it possible to build a compact pressure-boosting unit with a surface pump.
- Farms and allotments – the tank serves as a domestic water buffer and reduces pump load during frequent water use.
- Service companies – the certified butyl membrane and stainless steel connection simplify selecting a vessel for drinking water systems.
Application
The GBH FIX 100 diaphragm vessel is designed for water supply and pressure-boosting systems supplied from the mains or from an independent water source, where it stabilizes pressure and protects the pump against excessively frequent starts. The certified butyl membrane allows contact with domestic and drinking water.
The tank is installed horizontally and works with surface and submersible pumps, pressure switches, and control automation. The GBH FIX 100 diaphragm vessel reduces the effects of water hammer and evens out pressure fluctuations in the system.
Features of the GBH FIX diaphragm vessel – description and technical data
The GBH FIX 100 diaphragm vessel is a horizontal membrane tank with a steel body coated with a two-layer epoxy-polyurethane coating. Inside is a non-replaceable butyl membrane with high tensile strength and resistance to high temperatures, while the connection is made of stainless steel. The plastic base and feet limit the transmission of pump vibrations to the surface.
The membrane separates the water from compressed air, allowing the system to maintain stable pressure between successive pump operating cycles. The tanks meet the requirements of the PED 2014/68/EU Pressure Equipment Directive and the EN 13831 standard.

Frequently asked questions (FAQ) – IPRO GBH diaphragm vessel
What is the GBH FIX 100 diaphragm vessel used for?
The GBH FIX 100 diaphragm vessel stabilizes pressure in water supply and pressure-boosting systems and reduces the frequency of pump starts. The certified butyl membrane allows contact with domestic and drinking water.
What is the difference between a horizontal and a vertical tank?
A horizontal tank is installed in a lying position and often serves as the base of a compact pressure-boosting unit with a surface pump. A vertical version takes up less floor space and is available in larger capacities.
How do you select the capacity of a diaphragm vessel?
The capacity is selected based on the pump's output and the required number of starts per hour – the larger the tank, the less frequently the pump starts. If in doubt, we encourage you to contact Dambat's technical department.
What is the pre-charge pressure in the vessel, and can it be changed?
The vessels are supplied with factory-set air pre-charge pressure (2–2.5 bar, depending on capacity). This pressure can be adjusted to the pump start pressure using the air valve.
Is the GBH FIX diaphragm vessel suitable for drinking water?
Yes. The butyl membrane is certified for contact with water intended for human consumption, so the vessel can be used in domestic and drinking water systems.
Where can the GBH FIX diaphragm vessel be purchased?
Dambat does not sell directly. IPRO diaphragm vessels are available from trade partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the GBH FIX diaphragm vessel?
IPRO – 60 months (5 years) manufacturer's warranty. Warranty and post-warranty service provided by Dambat.
