Pressure Vessels

Pressure vessels are closed containers that hold liquids at a pressure that is different from the ambient pressure. They are used in pressure boosting and in boiler systems. These can be pressure cookers, bench sterilisers, autoclaves, steam generators, air compressors, boilers, and liquid nitrogen containers, among others.

The typical domestic use of a pressure vessel is in a pumped water system. When the pump starts, the pressure inside the vessel increases. When the vessel is full and the pump has reached its top pressure setting, the pump switches off. As water is drawn from the system, the air pressure around the membrane pushes water out of the vessel and into the pipework system. The minimum pressure is reached when the membrane is fully deflated. At this point the pump starts from its low setting and the cycle of pumping to the top pressure begins again.

Grundfos pressure vessels are long-life, maintenance-free tanks that are suitable for controlling the pressure in many domestic as well as industrial applications. They can be integrated into a variety of systems with pumps. There is a broad range of tank sizes available to suit any particular pressure requirement. The pressure tank itself is made of steel and factory-charged with nitrogen. All of the parts that may come into contact with water are made either of steel or coated with a corrosion-resistant material. The replaceable membrane in tanks of capacities exceeding 60 litres is made of high-quality rubber material that is suitable for potable water applications such as booster systems, pressurisation and water hammer arresting.
