All Grundfos Magna 3 Circulators
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 pump is characterised by the following:
|
The MAGNA3 is a single-phase pump.

Communication The MAGNA3 enables communication via the following:
|
Motor and electronic controller The MAGNA3 incorporates a 4-pole synchronous, permanent-magnet motor (PM motor). This motor type is characterised by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled

We have had tremendous success replacing aging booster systems in all types of buildings with Grundfos Booster Systems. Our projects have been as small as a single booster in small commercial spaces to the largest city high rises. Grundfos has a complete selection of booster systems and working with Hurley Engineering to size the right equipment for the correct application is always a professional a pleasurable experience. Hurley Engineering also always goes above and beyond helping with design assistance, energy rebates, and start up services. Fantastic Team!
