Welcome to National Pumps and Boilers. For professionals who demand reliability and efficiency, choosing the right components is everything. The Grundfos MAGNA3 is the intelligent heart of any modern heating, cooling, or domestic hot water system, designed to deliver outstanding performance without the headache.

The Last Word in Intelligent Water Circulation

Fit a pump and walk away with complete confidence. That’s the peace of mind the Grundfos MAGNA3 65-120FN brings to any building project, old or new. Engineered as a true "fit and forget" solution, it’s ideal for specifiers creating high-performance systems. Its clever canned-rotor design means the pump and motor form an integral unit without a failure-prone shaft seal, ensuring a long, reliable, maintenance-free service life. The bearings are even lubricated by the pumped liquid, a feature that speaks volumes about its robust durability.

The MAGNA3’s brain is what truly sets it apart. The game-changing AUTOADAPT and FLOWADAPT technologies constantly analyse system needs, adjusting performance in real-time to slash energy bills, perfect for environments with fluctuating demand. The FLOWADAPT feature also reduces the need for extra throttling pump valves, cutting component costs and saving installation time. For ultimate convenience, the intuitive display and built-in Bluetooth allow a direct connection to the Grundfos GO Remote app on your smartphone. Access advanced reporting and monitoring without extra dongles or climbing into cramped plant rooms.

This pump's versatility makes it a superior choice for many applications, establishing it as a go-to in our Commercial Circulators range. It provides stable temperature control for mixing loops and world-class efficiency for ground-source heat pumps. It also excels in air conditioning surfaces and smaller chiller applications, providing consistent flow. As one of our premier DHW Pumps, it guarantees reliable hot water recirculation. For advanced control, it includes fieldbus communication via CIM modules, plus analog and digital inputs, allowing seamless integration into larger Building Management Systems.
