MAGNA3 - More than a pump With its unrivalled efficiency, all encompassing range and built-in communication capabilities plus functionalities replacing system components, the MAGNA3 is ideal for engineers and specifiers looking to create high performance systems for buildings. This pump in the Grundfos master class will fit both heating and cooling applications perfectly, making it the obvious choice for almost any building project, old or new. The MAGNA3 is of the 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. The innovative clamp with only one screw enables easy repositioning of the pump head. The MAGNA3 is a pump with no maintenance requirements and with extremely low life cycle cost. The MAGNA3 incorporates a 4-pole synchronous, permanent magnet motor (PM motor). This motor type is characterized by higher efficiency than a conventional asynchronous squirrel cage motor. The pump speed is controlled by an integrated frequency converter. A differential pressure and temperature sensor is incorporated in the pump.
