Wet rotor circulation pump MAGNA3 40-80 F N 220 1x230V PN6/10 97924349

Grundfos MAGNA3 Circulation Pump – an efficient solution for your installation

The Grundfos MAGNA3 40-80 F is a wet-rotor circulation pump designed to force liquid circulation in heating, air conditioning and domestic hot water systems. Its construction based on a permanent magnet motor and electronic speed control guarantees high energy efficiency and reliable operation. It is an ideal solution for both new and modernized installations in residential, commercial and industrial buildings.

Construction and application

The MAGNA3 pump is characterized by a compact design and easy installation. Made of high-quality materials, such as stainless steel (housing) and carbon fiber reinforced composites (impeller), it ensures long-term operation even in difficult conditions. Thanks to the wide range of operating parameters, the pump works perfectly in installations with various characteristics – with constant or variable flow, with different medium temperatures. It can be used in mixing loops, underfloor heating systems, air conditioning installations and systems with a geothermal heat pump.

Advantages and benefits

• High energy efficiency: The permanent magnet motor and electronic speed control minimize electricity consumption, which translates into lower operating costs. The energy efficiency index (EEI) of 0.19 confirms its energy saving.
• Intelligent control: Built-in AUTOADAPT and FLOWADAPT functions automatically adjust the pump parameters to the current system needs, optimizing comfort and saving energy.
• Versatility: The ability to configure the pump for different operating modes (constant curve, constant temperature, proportional pressure) and a wide range of operating parameters make it a universal solution for many applications.
• Communication: Support for communication protocols such as PROFIBUS, RS-485, EtherNet/IP, Modbus RTU or BACnet MS/TP enables integration of the pump with building management systems (BMS) and remote monitoring of its operation. Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals.
• Reliability: Solid construction with high-quality materials and the lack of mechanical seals minimize the risk of failure and extend the pump's life.
• Quiet operation: The pump design ensures quiet operation, which is particularly important in residential buildings.
• Ease of use: The intuitive display makes it easy to configure and monitor the pump's operation.
