General description

The Grundfos GT-H, GT-C, GT-D, GT-DF and GT-CF are suitable for stabilising the pressure in domestic as well as industrial applications.

Fig. 1 Example of GT-H tank

Applications

• GT-H is a diaphragm tank for use in cold-water systems. The horizontal version has a base plate for mounting of a pump.
• GT-C is a composite tank for a wide range of applications.
• GT-CF is a composite tank with Flow Thru technology for use in cold-water systems.
• GT-D is a chlorine-resistant double-diaphragm tank.
• GT-DF is a double-diaphragm tank with Flow Thru technology.

The table below shows the tank types in relation to application.

Recommended

• Not recommended.
• Grey wastewater is domestic wastewater, for example from dishwashers, washing machines and cabinet showers.

Nameplate

Fig. 2 Example of nameplate

Installation

Before installation, check the following:

• Do the specifications of the GT tank correspond to the order?
• Are all visible parts intact?
• Is the maximum system pressure lower or equal to the maximum operating pressure for the GT tank? See tank nameplate.

Lifting the tank
The top of large tanks has a welded-on flange/nut in which a lifting eye can be fitted. When the tank is in place and secured to the floor, the lifting eye can be removed.

Location
Always install the GT tank in the discharge pipe as close to the pump as possible.

Install the GT tank in a frost-free room. It must be possible to inspect the GT tank from all sides.

The air-filling valve, water shut-off and dischargemust be accessible, and the nameplate must be visible.

Install the GT tank so that it is not stressed by thepipework. If vibrations are likely to occur, we recommend that the GT tank is installed so that vibrations are absorbed.

We recommend to follow these steps:

1. Lift and position the GT tank.
2. Level as required (horizontally and vertically).
3. Secure the GT tank.
4. Connect the pipes and fittings.
5. Check/adjust the precharge pressure.
6. Start the pump or application.

No additional loads from the piping system or equipment are allowed.

Floor installation

Large GT tanks must be secured to the floor by means of bolts. Use bolts, washers and nuts that are suitable for the surface of the floor or base frame.

Use all bolt holes in the base frame when securing the GT tank.

Tanks with steel bases should be mounted using the brackets supplied, while tanks with plastic bases should be mounted through the bolt holes in the base. For bases without bolt holes, drill four holes at equal distance in the rim of the base.

Fig. 3 Installation of tank with steel base

Fig. 4 Installation of tank with plastic base

Wall installation
Small GT tanks up to 33 litres must be secured to a wall or similar.

Fig. 5 Example of wall installation with wall bracket

Precharge pressure
The GT tanks are supplied from factory with a precharge pressure. See tank nameplate.

The precharge pressure must be adjusted according to the actual application and the installed pump.

It should be slightly below the pump cut-in setting.

Recommended precharge pressures:

• 0.9 x setpoint for fixed-speed pumps
• 0.7 x setpoint for variable-speed pumps.

Fig. 6 Precharge pressure

Adjusting the precharge pressure

Warning
Before starting work on the product, make sure there is no system pressure on the tank.

Disconnect pumps or switch off the power supply.

If the precharge pressure is not suitable for the application, adjust it as follows:

1. Switch off the pump. Open the nearest tap to make sure that no system pressure is affecting the reading.
2. Remove the protective cap.
3. Check the precharge pressure with a suitable pressure gauge.
4. Release or add air as required to make the precharge pressure equal to the recommended precharge pressure.
5. Fit the protective cap to prevent air from escaping from the tank.

Caution Never exceed the maximum operating pressure of the tank.

System check
The GT tank must be bypassed if the system pressure exceeds the maximum operating pressure of the GT tank during a system check.

Isolating valves
We recommend to install an isolating valve in connection with the GT tank.

Fig. 7 Isolating valves

Maximum operating pressure
The maximum operating pressure of the pump (p2) plus the actual inlet pressure (p1) must not exceed the maximum operating pressure of the GT tank (p3). See fig. 8.

See pump and tank nameplates.

Fig. 8 Maximum operating pressure

Relief valve

Install a relief valve. Set the relief valve to open at or below the maximum operating pressure of the GT tank. This will protect the GT tank and other system components. The relief valve should be installed at the connection of the GT tank to the pipe system and have a discharge equal to the pump capacity at maximum operating pressure.

Fig. 9 Relief valve

Maintenance

The GT tank is a maintenance-free, but we recommend to check it for damage two times a year:

• Is corrosion visible?
• Are there are any visible scratches, dents, etc.?

In case of serious damage, contact your nearest Grundfos company.

Technical data

See tank nameplate.

Fault finding

Warning
Before starting work on the product, switch off the power supply. Make sure that the power supply cannot be accidentally switched on.

Make sure that the tank is pressure less before removing it from the pipe system. Close the isolating valves and release the recharge pressure through the air valve.

according to section 4.3 Precharge pressure.
b) Diaphragm broken. Water escapes if the air valve is pushed down.| Replace the GT tank.
c) Leakage in pipework.| Check and repair the pipework

Disposal

This product or parts of it must be disposed of in an environmentally sound way:

1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest Grundfos company or service workshop.

Subject to alterations.
