Description
150 horizontal diaphragm tank – pressure vessel for water systems and pressure boosting systems
The 150 horizontal diaphragm tank is a pressure vessel designed for water systems and pressure boosting systems. Water is stored under pressure from an air cushion separated by an EPDM diaphragm, allowing the tank to stabilize system pressure and reduce how often the pump switches on. The body, made of carbon steel with a protective coating, ensures durability in typical water systems and pressure boosting systems.
Who it's for
- Plumbers and hydraulic fitters – a complete pressure vessel ready to connect to a pressure boosting system reduces water system installation time.
- Homeowners with their own water source – the tank stabilizes pressure from the well and reduces the number of pump cycles, extending the pump’s service life.
- Farms and properties without a mains water supply – a reserve of pressurized water makes pump-fed systems more convenient to use.
- Technical service – the EPDM diaphragm and simple design make it easy to check the pre-charge pressure and carry out routine maintenance.
Applications
The 150 horizontal diaphragm tank works with a pump in a pressure booster set, storing water under pressure and supplying it to the system between pump cycles. This keeps water pressure steady and reduces how often the pump switches on, limiting wear and reducing pressure fluctuations in the system.
The horizontal design makes it easy to fit into compact pressure booster sets and helps save space in the utility room. The tank is suitable for domestic and agricultural water systems supplied by surface or submersible pumps, typical of buildings using their own water source in Poland. It is ideal wherever a durable 150 horizontal tank is needed.
Features, description and technical data – 150 horizontal tank
Inside the tank is an EPDM diaphragm that separates the water from the air cushion. Compressed air on one side of the diaphragm maintains pressure and pushes water into the system when the pump is not running. The body is made of carbon steel with a protective coating, which protects the tank against corrosion and ensures durability at the operating pressures typical of pressure booster systems.
The tank is supplied with a factory pre-charge pressure of 1.7 bar ±10% and operates at a maximum working pressure of 8 bar, within a temperature range of 0°C to 70°C. The 1" water connection makes it easy to connect to standard pressure booster sets and water systems. The pre-charge pressure should be adjusted to match the pump’s cut-in pressure.

Frequently asked questions (FAQ) – 150 horizontal tank
What is the IBO 150 horizontal tank used for?
The IBO 150 horizontal diaphragm pressure tank stabilizes pressure in a water system and pressure booster set. It stores water under pressure from an air cushion separated by an EPDM diaphragm and supplies it to the system, so the pump switches on less often.
What is the difference between the steel (coated) version and the INOX version?
In the standard version, the body is made of carbon steel with a protective coating, while the INOX version is made of corrosion-resistant AISI 304 stainless steel. The INOX version is worth considering for more aggressive water or when greater body durability is required.
Is the 150 horizontal tank suitable for my pressure booster system?
The tank with an EPDM diaphragm is designed for domestic water in pressure booster systems operating at up to 8 bar. The factory pre-charge pressure of 1.7 bar is adjusted to suit the specific pump – it is set slightly below the pump’s cut-in pressure so the tank can effectively reduce how often the pump switches on.
How do I set the pre-charge pressure in a diaphragm pressure tank?
The pre-charge (air) pressure is set when the tank is empty, usually about 0.2 bar below the pump’s cut-in pressure. The factory setting is 1.7 bar ±10%. Correctly set pre-charge pressure ensures proper diaphragm operation and stable water pressure in the system.
Where can I buy a Dambat 150 horizontal tank?
The manufacturer does not sell directly. The 150 horizontal diaphragm pressure tank is available from trade partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the 150 horizontal tank?
The IBO 150 horizontal diaphragm pressure tank comes with a 24-month (2-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
