Grundfos MAGNA3 40-120 F Circulating Pump

The Grundfos MAGNA3 40-120 F circulator pump, reference 97924270, is an advanced solution designed for heating and cooling systems in commercial buildings. This pump stands out for its energy efficiency, wide operating range, and advanced communication capabilities, making it a high-performance choice for commercial applications that require precise control, continuous monitoring, and adaptability. Grundfos, a global leader in pump manufacturing, has developed this pump as the ideal option for integration into a wide variety of construction projects seeking efficient and reliable systems.

Energy efficiency and advanced technologies:

The Grundfos MAGNA3 is equipped with the latest energy efficiency technologies and intelligent control. Its average energy efficiency index (EEI) is below 0.19, ensuring reduced energy consumption and economical operation in the long term. With a maximum input power of 427 W, the pump is designed to minimise 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 optimising its operation. Additionally, the FlowAdapt function eliminates the need for throttle 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 according to the system's needs, maximising 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 seamless integration with the centralised management system, offering full control over the pump's performance, which is especially useful in large commercial installations.

The pump also includes a colour display with 3D infographics, facilitating direct configuration and monitoring of the pump. Additionally, the Grundfos Eye system provides real-time visual information on the pump's status, allowing users to immediately identify any issues.

Hydraulic performance:

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

This pump is designed to operate with a liquid temperature range from -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 service life, 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 service life and minimises 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, extending the equipment's service life.

Communication and advanced control capabilities:

The MAGNA3 is equipped with a configurable analogue 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.
