What are pressure tanks?
Pressure tanks are devices designed to store water under specific pressure. Their main task is to ensure stable pressure in water systems, which is crucial for the proper functioning of the installation. Solutions of this type are used both in household filtration setups and in more advanced water treatment systems.
In reverse osmosis systems, the tank stores purified water so that it is available immediately after turning on the faucet. Thanks to this, the user does not have to wait for the osmotic membrane to produce the required amount of water at that moment.
Key benefits and applications
Pressure tanks are used in various applications — from standard household systems to industrial installations. Their presence translates into more convenient water use and better organization of the entire system's operation.
Water storage under pressure — enables quick water withdrawal whenever it is needed.
Stable system operation — helps maintain the continuity of the water installation.
Support for RO and nanofiltration systems — allows filtered water to be stored and ensures its constant availability.
Use in household and industrial installations — a wide range of capacities and designs makes it easier to match specific needs.
Corrosion resistance — properly selected materials increase the tank's durability.
Ease of installation and operation — important in both new and upgraded systems.
A properly selected tank improves the comfort of using filtered water.
Types of pressure tanks
Hydrophore tanks
Hydrophore tanks are used to store water from a private intake, most often from a well, under pressure. Thanks to this, they can support the efficient use of water in household and industrial systems.
Reverse osmosis and nanofiltration tanks
Specialized pressure tanks for reverse osmosis and nanofiltration systems ensure an uninterrupted supply of clean water. They allow convenient storage of filtered water and help improve water quality in everyday use. The use of corrosion-resistant materials translates into their service life and reliability.
Materials and construction
The tanks available in this category are made from materials selected for durability, corrosion resistance, and the ability to operate under high pressure. In practice, the tank material has a direct impact on its service life and range of applications.
Stainless steel
Stainless steel tanks stand out for their high corrosion resistance and great mechanical strength. This is a good choice for applications in which the water may contain more aggressive chemical compounds.
Carbon steel
Tanks made of carbon steel perform well where resistance to high pressure is the key parameter. For this reason, they are also widely used in many industrial applications.
Plastics
Models made of plastic are lightweight, corrosion-resistant, and easy to install. The source offer includes, among others, the 3.2G 12L tank, which, thanks to its low weight and durability, works well wherever ease of installation and reliable operation in various conditions matter.
The use of a diaphragm in tanks provides additional protection against corrosion and contributes to a longer service life of the entire solution.
The material and construction of the tank are of great importance for the durability of the system.
How do pressure tanks work?
The operating principle of a pressure tank is based on storing water under pressure, often with the involvement of a pump. Water enters the tank, where it remains under pressure maintained by compressed air. When the system needs water, the pressure enables it to flow out of the tank, ensuring continuity of supply and convenience of use.
Scope of applications
Reverse osmosis systems — for collecting high-purity water and convenient withdrawal.
Nanofiltration — for storing filtered water free from many contaminants and undesirable substances.
Household water installations — wherever pressure stability and user comfort matter.
Industrial systems — for storing water under high pressure in technological processes.
How to choose the right pressure tank?
Tank selection should be based on several basic criteria. This helps avoid compatibility issues and match the product to the actual intensity of use.
