Pressure tanks

Drinking water tanks: Innovative solutions for your independent home.


Diaphragm pressure tanks are essential equipment in the field of water storage for reverse osmosis systems. These tanks make it possible to supply water continuously, on demand, while maintaining a constant pressure.



What is a diaphragm pressure tank?


Operation of a pressurized bladder tank

A bladder pressurized tank is designed to store water under pressure and distribute it in a regulated manner. Here's how it works:

  • Water Storage: When your reverse osmosis system produces water, it is routed to the pressurized tank. The tank then fills to full capacity thanks to the RO system.
  • Air bladder: The tank is equipped with a special air bladder which separates the water from the air. This bladder compresses when the tank fills with water, which keeps the pressure inside the tank constant.
  • Water Dispensing: When you open your RO water dispenser, water is delivered from the tank through the air bladder. This design makes it possible to have a constant pressure and an even distribution of water.

Advantages of the diaphragm pressure tank


Bladder pressurized tanks offer many advantages in water storage systems. Here are the main ones:


  1. Continuous distribution: Thanks to their design, the pressurized tanks make it possible to supply water continuously, on demand. This means you always have water available when you need it, without interruption.
  2. Constant pressure: Pressurized tanks maintain a constant pressure inside the system, which guarantees an even distribution of water. So you can enjoy a constant flow without pressure fluctuations.
  3. Versatility of use:

Our pressurized tanks can be used in different applications:

  • Rainwater storage: You can use our 60L or 100L pressurized tanks to store rainwater or previously treated and sterilized borehole water, to meet your daily water needs by contributing thereby saving water and reducing your environmental footprint.
  • Increased storage capacity: You have the option of connecting multiple tanks to increase the storage capacity of your reverse osmosis system.
  • Standards Compliance: Bladder pressure tanks are manufactured to strict FDA standards (CFR - Part 177, 2018). They are also tested by independent third parties to NSF/ANSI standard (61 for potable water system components) to ensure material safety and structural integrity.
  • High Maximum Working Pressure: All pressurized tanks have a maximum working pressure of 100 Psi. This means they can withstand high pressures without compromising their structural integrity.


By opting for a pressurized diaphragm tank, you are choosing a reliable solution that complies with the strictest safety standards. Enjoy efficient and versatile storage to meet your water needs, whether as part of a reverse osmosis system or for rainwater conservation.
