The MAGNA3 and UPE ranges consist of a wide assortment of small, medium and large-sized circulator pumps with communications equipment and motors with electronic speed control that integrate permanent magnet (PM) and compact stator technology.

The innovative MAGNA3 range is part of Grundfos' family of exceptional quality circulators.

Thanks to MAGNA3 pumps, you can completely forget about the need for complex adjustments. Install the pump and use the factory setting: the AUTOADAPT function (MAGNA3 range only).

The installed MAGNA3 pump will automatically perform an analysis of the heating system, find the optimal set point and continuously regulate its operation to adapt to changes in demand. This will allow you to enjoy maximum comfort and minimum energy consumption. In addition, MAGNA3 pumps are extremely flexible and reliable, generate low noise levels, achieve long service lives and are maintenance-free. They incorporate infrared communication devices and allow the use of external control and monitoring functions through the use of expansion modules.
