Grundfos GT-H vertical diaphragm pressure vessels store water under pressure to reduce pump cycling and help stabilise pressure in compatible booster, borehole and water-supply systems. These steel vessels use a butyl-rubber diaphragm and polypropylene liner to separate the air and water chambers.

Available 10 bar variants

• GT-H-8-V, 8 litre, 1 in connection
• GT-H-60-V, 60 litre, 1 in connection
• GT-H-80-V, 80 litre, 1 in connection

Selection and installation

The GT-H range is designed for drinking-water applications, with a stated liquid-temperature range of 0 to 90°C. Select the vessel volume for the pump duty and system demand, then set the pre-charge to suit the control pressure before commissioning. Confirm connection orientation, available space and local water regulations.
