Grundfos - GT-HR-300 Vertical Hot Water Diaphragm Tank - 6 Bar. - 300 Ltr

Grundfos GT-HR are pressure tanks with a capacity ranging from 8 to 1000 litres. The tanks are designed for a maximum operating pressure of 6 bar and a maximum liquid temperature of 90 °C.

The tank is a steel pressure tank with a non-replaceable rubber diaphragm for heating applications. The tanks have a non-replaceable diaphragm, dividing the tank chamber into two compartments: the upper compartment is pre-charged with compressed nitrogen (1.5 bar) while the lower compartment contains the diaphragm itself, which is a polypropylene (PP) liner.

A pressure tank ensures controlled pressure in the water supply and thereby limits the switching frequency of the pump unit in case of low water consumption or loss due to leakage. This ensures increased comfort in your installation by limiting the start and stop frequency of your pump. It also creates a more stable assembly by compensating for pressure drops when a tap is opened, while reducing problems with water hammer in the pipes.
