Circulation pump Grundfos MAGNA3 100-60 F PN6

The Grundfos MAGNA3 circulation pump is the ideal choice for almost any building project, old or new. With its unrivaled energy efficiency, comprehensive range, and built-in communication capabilities, the MAGNA3 is ideal for engineers and designers who want to create high-performance heating and cooling systems. The pump is maintenance-free thanks to its encapsulated rotor design. This also means that the pump and motor form an integral unit with no shaft seal and only two gaskets for sealing. The bearings are lubricated by the pumped liquid. The MAGNA3 has an intuitive display and allows it to connect wirelessly with the Grundfos GO Remote app, giving access to advanced reporting and monitoring. The pump includes fieldbus communication via CIM modules, analog and digital inputs, and configurable relays. Control features include FLOWADAPT, which reduces the need for throttle valves, thus cutting costs on system components.
