Fluctuating water pressure is often seen as a minor issue. In reality, it can force pumps to work harder, increase energy consumption, and accelerate wear on the entire piping system. One of the key components that helps maintain stable system performance is a pressure tank.
A pressure tank acts as a pressure-balancing device within a water pumping system. It helps maintain a consistent water supply while reducing the frequency of pump cycling, preventing the pump from starting and stopping excessively.
Global Water Solutions (GWS) offers a wide range of pressure tanks designed for residential, commercial, industrial, and high-rise building applications. Each series is engineered with specific features to meet different system requirements.
A pressure tank stores water and maintains stable pressure within a water distribution system. Engineers commonly install it alongside pumps in booster systems and pressure-controlled water supply networks. Inside the tank, air and water are separated by a diaphragm or membrane. As water enters the tank, the air chamber becomes compressed, creating stored pressure.
This compressed air then pushes water back into the system whenever there is demand. As a result, the pump does not need to start every time a faucet is opened or a small amount of water is required. This process helps ensure a smoother and more consistent water supply, especially in multi-story buildings and systems with varying water demand throughout the day.
Many pump-related problems occur because pumps cycle too frequently. Over time, excessive start-stop operations can reduce pump efficiency and shorten equipment lifespan. A pressure tank minimizes pump workload by storing pressurized water within the system. When water demand is low, the stored pressure can supply water without immediately activating the pump.
Some of the key benefits of using a pressure tank include:
Pressure tanks are commonly used in booster pump systems, irrigation systems, thermal expansion applications, heating systems, and water distribution networks for commercial and industrial facilities.
The operating principle of a pressure tank is relatively simple. When the pump is running, water enters the tank and compresses the air inside. This compressed air becomes a stored energy source that pushes water back into the system whenever it is needed. As system pressure drops to a predetermined level, the pressure switch automatically activates the pump to refill the tank. Once the target pressure is reached, the pump shuts off.
Because the tank stores pressure between pump cycles, the pump does not need to run continuously. This results in a more efficient and reliable system. Modern pressure tanks, such as those manufactured by Global Water Solutions, use high-quality butyl diaphragms or membranes to separate air and water. This design helps maintain water quality while reducing the risk of internal corrosion.
Global Water Solutions offers several pressure tank series designed for different operating conditions, pressure requirements, and applications.
PressureWave™ is one of Global Water’s most popular pressure tank series.. It is designed for general applications such as booster systems, irrigation systems, and hydraulic hammer arresting. The PressureWave™ Series features a diaphragm design combined with a virgin polypropylene liner and a stainless steel water connection.
This construction helps ensure leak-free operation while minimizing maintenance requirements. In addition, the tank is protected by a dual-layer polyurethane paint finish for enhanced durability.
Users can choose inline, horizontal, and vertical configurations with capacities ranging from 2 to 150 liters.
Typical applications include:
The Challenger™ Series delivers greater durability and long-term performance for demanding applications. It utilizes patented CAD-2 diaphragm technology, which improves air and water separation inside the tank.
This advanced design reduces diaphragm stress and wear, helping extend the service life of the tank. The Challenger™ Series also features a stainless steel water connection and a polyurethane epoxy-primed paint finish for added protection.
Typical applications include:
Users can select Challenger™ tanks in capacities ranging from 60 to 450 liters.
The C2-Lite CAD™ Series offers a lightweight composite alternative to traditional steel tanks. It incorporates CAD-2 diaphragm technology and a fiberglass-reinforced structure sealed with epoxy resin, providing excellent resistance to harsh environmental conditions.
Because of its lightweight construction, installation is easier and more practical. The composite material also offers superior corrosion resistance, making it ideal for humid environments and outdoor installations.
Key advantages of the C2-Lite CAD™ Series include:
Global Water offers this series in capacities from 60 to 450 liters with a maximum working pressure of 8.6 bar.
For high-pressure systems and large-capacity requirements, Global Water offers the SuperFlow™ Series. Engineers commonly install these tanks in high-rise buildings, hotels, hospitals, and commercial facilities.
The SuperFlow™ Series offers pressure ratings of 10, 16, and 25 bar with capacities of up to 10,000 liters. Its interchangeable membrane design allows membrane replacement when necessary. Selected models also include a built-in pressure gauge for easier system monitoring and maintenance.
Typical applications include:
Global Water engineers the ASME Series to meet the standards established by the American Society of Mechanical Engineers (ASME). Global Water developed these pressure vessels specifically for industrial and heavy-duty applications.
The ASME Series features a carbon steel tank shell, interchangeable membrane design, and radiographically tested weld joints to ensure reliability and safety. Available pressure ratings include 10, 16, and 25 bar, with capacities reaching up to 3,000 liters.
Common applications include:
Selecting the right pressure tank involves more than simply choosing a tank size. Several factors should be considered to ensure optimal system performance.
Always select a tank with a pressure rating that matches your system requirements. Standard applications typically require 8.6 to 10 bar, while industrial facilities and high-rise buildings may require 16 to 25 bar.
Larger pumps and higher water demand generally require larger pressure tank volumes to achieve efficient system operation.
Steel tanks are suitable for most commercial and industrial applications, while composite tanks are often preferred in humid or outdoor environments due to their superior corrosion resistance.

Cooling Tower: Function, Working Principle, Types, and Key Components in Industrial Systems
In many industrial systems, one of the most common issues is actually quite simple: unstable temperature. Cooling water that is supposed to support system performance can gradually become too hot, increasing the workload of equipment and reducing overall efficiency. If this condition is left unmanaged, it can lead to more serious problems. Not only does […]
