Product description

The Grundfos Magna3 40-80 F is a circulation pump from the Grundfos MAGNA3 series. This series of circulation pumps is suitable for the following situations and applications:

  • Heating
  • Air conditioning
  • Cooling
  • Household systems for warm tap water
  • Geothermic heat pump systems
  • Solar heat systems

Because of new technologies, such as the FLOWLIMIT and FLOWADAPT in combination with the AUTOADAPT, this circulation pump is a lot more energy-efficient compared to Grundfos's older models. Additionally, this circulation pump can be easily integrated into building management systems.

Built-in energy monitor
The built-in energy monitor helps prevent high electricity bills as a result of an imbalance in the system. This is because this monitor checks the distribution and usage of heat energy in the system, with an accuracy of ± 1-10% (depending on the setting). This makes it unnecessary to install a separate energy monitor in the system

Pump configuration / status
The MAGNA3 has a TFT screen to control all aspects of the pump and which also shows the pump's performance. This pump also has a 'Grundfos eye' that shows the current status of the pump (in operation/in error)
