Wet rotor circulation pump MAGNA3 100-120 F 450 1x230V PN10 97924325

Product features

Grundfos MAGNA3 circulation pump is an advanced solution designed for efficient water circulation in heating and cooling systems, both in residential and commercial buildings. It is characterized by high efficiency, flexibility and the ability to adapt to changing operating conditions. Thanks to the integrated controller, the pump automatically adjusts its parameters, minimizing energy consumption and ensuring optimal user comfort. This is particularly important in installations with thermostatic valves, where precise flow control translates into real savings.

Design and application

The MAGNA3 pump has been designed with easy installation and maintenance in mind. Made of high-quality cast iron (GG 25), it provides durability and corrosion resistance. The pump connections with a round shape facilitate connection to the piping installation using flanged connections (EN 1092-2). The installation length of 450 mm allows the pump to be used in various installation configurations. High energy efficiency (EEI 0.17) and the ability to adjust the rotational speed make the pump ideal for modern heating and cooling systems, where reducing operating costs is key.

Functionality and communication

The MAGNA3 pump offers a wide range of control and communication functions, making it a versatile tool for professionals involved in hydraulic installations. It supports communication protocols such as PROFIBUS, RS-485, EtherNet/IP, Modbus RTU and BACnet MS/TP and LON/LONWorks, enabling integration with building management systems (BMS). Additionally, it is equipped with 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals for remote monitoring and control. The integrated controller allows operation in proportional pressure control, constant pressure, constant temperature and constant characteristic curves modes. The FLOW LIMIT function prevents exceeding the nominal flow, eliminating the need for additional throttling valves. The pump also has a potential-free switching contact to facilitate integration with external alarm systems.
