The Grundfos MAGNA3 pump is part of a series of economical and high-quality pumps. It is the successor of the original series MAGNA pumps. The pump has a number of automatic functions that contribute to the maximum efficiency and economical operation. Another advantage is the ability to communicate using IR wireless technology and to operate and monitor using a smartphone (you need to purchase a module that allows the communication).

The pump meets the EuP requirements.


With the AUTOADAPT function, the pump analyzes the requirements of the heating system and responds to its changes by adapting its performance. For each change of condition, the pump reacts by changing its operating point. Thanks to this feature, optimal comfort is ensured along with the power saving energy.

The FLOWLIMIT feature allows you to set the maximum flow limit. The pump continuously monitors the flow rate of the liquid and ensures that the required flow is not exceeded under stable operating conditions. It contributes to the balance of the whole system and reduces the need for balancing valves.

The FLOWADAPT is a combination of the two above functions. Enables further savings of energy.


  • Circulation of liquids in heating systems.
  • Air conditioning and cooling applications.
  • Hot water circulation system.
  • Solar systems.
