Product description

The Grundfos Magna3 40-120 F, a circulation pump in the latest Grundfos Magna3 series, has been designed for the following situations and operations:

  • Heating
  • Air conditioning
  • Cooling
  • Domestic hot tap-water systems
  • Geothermal heat pump systems
  • Solar-powered systems

By means of the latest technologies, such as the FLOWLIMIT and FLOWADAPT in combination with the AUTOADAPT, this circulation pump saves considerably more energy than the older Grundfos models. Furthermore, this circulation pump can easily be integrated into building management systems.

Built-in energy meter

The built-in energy meter prevents energy bills from running too high due to an imbalanced system. The meter monitors distribution and consumption of thermal energy within the system, to an accuracy of approximately 1% to 10% (depending on the working point). As a result, no separate energy meter is needed within the system.

Pump configuration / status

The Magna3 has a TFT display, which allows for full control of the pump and provides details about the pump's performance, /and is also fitted with a 'Grundfos Eye' indicator light that provides information about the actual pump status (in operation / error).
