Grundfos Steel Pressure Tanks

Product Code: N/A

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.

The GT-H tanks are steel pressure tanks with a non-toxic butyl rubber diaphragm with a precision-moulded polypropylene liner for superior air and water separation. Recommend application: Drinking water.

The Grundfos Steel Pressure Tanks come factory pre-charged 10 bar= 1.9 bar (pre-charge) / 16 bar = 4 bar

  • GT-H – Single Diaphragm
  • GT-D – Double Diaphragm
  • GT-U – Replaceable Diaphragm


  • Wide range of GT tanks – The GT tanks are available in sizes from 8 to 5,000 litres, suitable for vertical installation. GT tanks in sizes 24 to 80 litres are also suitable for horizontal installation.
  • Approved for drinking water – The Grundfos GT tanks are approved for use with drinking water.
  • Reducing start / stop frequency – The GT tanks ensure controlled pressure in the water supply and thereby limit the switching frequency of the pump incase of low water consumption or leakage loss.
  • Optimise comfort – The GT tanks increases system comfort by compensating for pressure drops when a tap is opened and reduces problems with water hammer in the pipework
