Energy efficiency and advanced technologies:

The Grundfos MAGNA3 is equipped with the latest energy efficiency and intelligent control technologies. Its average energy efficiency index (EEI) is less than 0.19, ensuring reduced energy consumption and economical long-term operation. With a maximum input power of 427 W, the pump is designed to minimize energy use while maintaining optimal performance.

Among its most advanced features, the MAGNA3 includes the AutoAdapt function, which automatically adjusts the pump to the system's characteristics, continuously optimizing its operation. Additionally, the FlowAdapt function eliminates the need for throttling valves, reducing installation and maintenance costs, and simplifying system setup. The combination of these intelligent functions allows the pump to automatically adjust its flow and pressure based on the system's needs, maximizing efficiency and energy savings.

Control and monitoring capabilities:

One of the main features of the Grundfos MAGNA3 is its ability to connect to building management systems (BMS) via optional CIM modules. This allows for seamless integration with the centralized management system, providing complete control over the pump's performance, which is especially useful in large commercial installations.

The pump also includes a color display with 3D infographics, making it easy to configure and directly monitor the pump. Additionally, the Grundfos Eye system provides real-time visual information about the pump's status, allowing users to identify any issues immediately.

Hydraulic performance:

The MAGNA3 40-120 F offers a nominal flow rate of 14.14 m³/h and a nominal head of 7.263 meters, making it an ideal option for heating, cooling, and other water circulation applications in commercial buildings. Thanks to its robust and efficient design, it can handle large volumes of water and provide stable and reliable circulation at all times.

This pump is designed to operate with a liquid temperature range of -10°C to 110°C, making it suitable for a wide range of applications, from heating systems to cooling circuits. The ideal operating temperature is 60°C, ensuring efficient performance in most commercial applications.

Robust design and high-quality materials:

The pump body is made of cast iron (EN 1561 EN-GJL-250, ASTM A48-250B), providing high corrosion resistance and a long lifespan, even in demanding conditions. The impeller is made of composite, ensuring durability and wear resistance. This wet rotor design allows the pumped liquid to lubricate the bearings, reducing friction and wear, which extends the pump's lifespan and minimizes maintenance.

Easy installation and maintenance:

The Grundfos MAGNA3 40-120 F is designed for quick and easy installation. It has a port-to-port length of 250 mm and uses DIN connections (DN 40), making it compatible with a variety of piping systems. The maximum working pressure of 10 bar ensures that the pump can handle high pressures without compromising its performance or safety.

Maintenance is minimal thanks to its intelligent design, and its Night Mode automatically adjusts the pump to reduce energy consumption when demand is low, prolonging the equipment's lifespan.

Communication capabilities and advanced control:

The MAGNA3 is equipped with a configurable analog input and supports multiple communication protocols via optional CIM cards, making it highly adaptable to various system configurations. The pump can be controlled wirelessly and offers advanced functions such as proportional pressure control, constant temperature control, and FlowLimit, ensuring that the pump operates efficiently at all times.
