Grundfos GT-D Steel Pressure Tanks with Double Diaphragm (130-450 Litre) - Pre Charged

GT-D is a steel pressure tank with double diaphragm designed for drinking water use. The diaphragm is made of chlorine-resistant 100 % butyl with copolymer polypropylene liner for air and water separation.

The tank is a steel pressure tank with double diaphragm. The diaphragm is a chlorine-resistant 100 % butyl diaphragm with a precision-moulded copolymer polypropylene liner for superior air and water separation.

The diaphragm is a chlorine-resistant 100 % butyl diaphragm with a precision-moulded copolymer polypropylene liner for superior air and water separation. The tank has a FlowThru connection, which constantly flushes the tank while the pump is running. This ensures that the water in the tank remains fresh and eliminates the risk of stagnant water during normal system operation.

The tanks have a non-replaceable diaphragm that is pre-charged with nitrogen (1.5 bar). The tanks have a non-toxic butyl rubber diaphragm, dividing the tank chamber into two compartments. The upper compartment contains compressed nitrogen. The lower compartment has a liner of polypropylene (PP) and is filled with water from the pump.

A pressure tank ensures controlled pressure in the water supply and thereby limits the switching frequency of the pump in case of low water consumption or leakage loss. The result is increased comfort in your installation by limiting the start/stop frequency of your pump, and it increases system comfort by compensating for pressure drops when a tap is opened, while reducing problems with water hammer in the pipework.
