Grundfos MAGNA3 D 40-40 F

Running a large commercial building comes with its own set of pressures, and a faulty heating or cooling system shouldn't be one of them. You need a circulator pump that works quietly in the background, keeping everything running smoothly without a fuss. That’s exactly what the Grundfos MAGNA3 D 40-40 F is designed to do, offering smart, reliable performance you can count on day in and day out.

Smart, Efficient, and Built to Last

In any commercial environment, the failure of a critical component can lead to significant disruption and costly emergency repairs. The reliability of your heating and cooling system is paramount. The Grundfos MAGNA3 D is engineered as the definitive solution to this challenge. Its intelligent twin-head design provides a level of operational security that a standard single-pump setup simply cannot offer, making it an essential asset for any facility manager.

Its reliability stems from two wirelessly communicating pump heads, offering double performance and peace of mind. They operate in three multi-pump modes: Alternating (sharing workload to extend service life), Backup (one pump on standby for instant takeover, eliminating downtime), and Cascade (both pumps working in unison for high demand).

Beyond its reliability, the MAGNA3 D is engineered to be incredibly efficient. The brilliant AUTOADAPT technology constantly analyses the system’s requirements and adjusts its performance, ensuring it only uses the precise amount of energy needed. This leads to substantial savings on energy bills without manual intervention. The FLOWLIMIT function also provides granular control to optimise your system perfectly.

With its robust cast iron construction, this pump is truly built to last. Its versatility makes it the ideal heart for a wide range of demanding systems, from commercial heating and air conditioning to domestic hot water recirculation and large-scale district heating networks. It is a prime example of a top-tier commercial circulator that delivers on every front. For a complete installation, consider compatible accessories like the Grundfos GO Remote for advanced control, alongside essential components like our high-quality pump valves.
