GT diaphragm and bladder pressure tanks



The GT pressure tanks for cold-water applications are longlife tanks for both domestic and industrial applications. The GT tank ensures controlled pressure in your water supply. The result of this is better comfort in your installation by limiting the start / stop frequency of your pump, compensation for pressure drops and eliminating water hammer in pipework. GT tanks can be integrated in many different installations with a wide variety of pumps. Grundfos offers a large range of tank types and sizes, ensuring the best possible tank for your installation.
