Product Details

The SuperFlow series pressure tanks feature an interchangeable membrane design, allowing for easy replacement of the membrane as needed. This design ensures long-term flexibility and ease of maintenance. Larger models come equipped with a built-in pressure gauge, enabling efficient pressure monitoring and precise system pressure control. Designed to the EN13831:2007 technical standard and produced in accordance with the Pressure Equipment Directive 2014/68/EU, these tanks guarantee premium quality and reliability for all your high-pressure applications.

Pressure tanks with replaceable membrane

SuperFlow™ pressure tanks are ideally suited for applications where high volumes and high pressure ratings are required. Engineered to meet the most rigorous system demands, SuperFlow tanks are perfect for use in pressure booster systems, hot water circulation systems, and water hammer arresting in high-rise and multistory buildings—including hotels, hospitals, or business centers.

The interchangeable membrane design ensures long-term flexibility and ease of maintenance. It allows the end user to replace the membrane when needed, increasing tank longevity. The built-in pressure gauge (included in 100 L / 26.4 G models and above) supports efficient pressure monitoring, allowing real-time tracking of internal conditions.

Manufactured in a GWS SuperFlow-dedicated ISO9001, ISO14001, and ISO45001 approved facility, each tank is quality tested at several stages of the production process to ensure premium quality and system safety. The SuperFlow series is designed according to EN13831:2007 and complies with the Pressure Equipment Directive 2014/68/EU, supporting dependable system pressure control.

With SuperFlow series tank volumes ranging from 50 – 10,000 L / 60 – 2,640 G, the series represents one of the most versatile and comprehensive pressure tank offerings worldwide.
