GT tanksGeneral data
ApplicationsThe Grundfos GT diaphragm and bladder pressure tanks are suitable for domestic and industrial applica-tions where a controlled pressure is required.
Operating pressure
Liquid temperature
Typical applications:• domestic water supply systems• booster systems• irrigation systems• industrial systems.The Grundfos GT tanks are approved for use with pota-ble water.
The GT tanks can be used with any Grundfos pump.
Type key
Tank rangeThe GT tanks are available in sizes from 8 to 3000 litres suitable for vertical installation. GT tanks in sizes 24 to 80 litres are also suitable for horizontal installation.
The GT-H tanks have a non-toxic butyl rubber dia-phragm, dividing the tank chamber in two compart-ments. The upper compartment contains compressed nitrogen. The lower compartment has a liner in polypro-pylene (PP) and is filled with water from the pump. The GT-D tanks have a double diaphragm.
The GT-U tanks have a replaceable, non-toxic butyl rubber bladder surrounded by compressed nitrogen. The bladder is the only component in contact with the liquid.
GT-H and GT-D Max. 10 barGT-U Max. 16 barGT-U-8 V Max. 25 bar
GT-H and GT-D Max. 90°CGT-U Max. 70°C

General data GT tanks
SizingThe required tank capacity can be calculated as fol-lows:
Capacity
V = Tank volume [litres]Q = Mean flow rate [m3/h]Δp = Difference between cut-in and cut-out
pressure [bar]Cut-in = Cut-in pressure (lowest) [bar]nmax = Max. number of starts/stops per hourk = Constant for tank pre-charge pressure:
k = 0.9.
Pumps fitted with a Grundfos MGE motor: Please refer to the Hydro 2000 data booklet.
The diagram below is based on the following values:
• differential pressure Δp: 1 bar• number of starts/stops per hour: 20• k = 0.9.Note: Tank sizes larger than 450 litres should be calcu-lated by means of the formula above.
