Grundfos - Magna1 40-120FN 98254920 Circulator Pump - 230V - OBSOLETE - Cast Iron

The Grundfos MAGNA1 is a circulator pump unit with permanent magnet motor and straightforward selection of pump setting. The MAGNA1 will fit both heating, cooling and domestic hot water circulation applications perfectly, making it the obvious choice for almost any building project – old or new.

The pump is a canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing.

The bearings are lubricated by the pumped liquid. A pump with no maintenance requirements and extremely low life cycle cost.

The pump has an intuitive user interface, which is especially fit for replacement of older circulators. The well-suited choice for basic performance needs in applications where system communication is not required.
