Grundfos Magna 1 FN

The Grundfos Magna 1 system is designed to circulate liquids in heating systems with variable flows where it is desirable to enhance the settings of the pump duty point.

Easy-to-use, with an A-Rated/EuP-Ready variable speed circulator and pump selection setting, this pump has low maintenance requirements and an extremely low life-cycle cost. 

The pump is also suitable for systems with hot-water priority, as an external signal can immediately force the pump to operate according to the max. curve (eg in solar-heating systems).

Our wide range covers a number of options with varying bar rating pressures.
