Wet rotor circulation pump MAGNA3 100-100 F 450 1x230V PN10 97924324

Flangeless circulation pump for heating and cooling systems

The Grundfos MAGNA3 100-100 F 450 is a high-performance device designed for circulating water in heating and cooling systems, both in residential and commercial buildings. Its design based on a flangeless technology ensures quiet operation and minimizes the risk of failure. The pump is equipped with an integrated controller that automatically adjusts the performance to the current needs of the installation, which translates into energy savings.

Construction and application

The MAGNA3 pump is versatile and can be used in various types of installations, including systems with heat exchangers, fan coil units and cooling surfaces. Thanks to the possibility of adjusting the rotational speed, the pump ensures optimal operating parameters regardless of changing conditions. Made of high-quality cast iron (GG 25), it provides durability and corrosion resistance. Flanged connections (EN 1092-2) facilitate installation and integration with existing infrastructure. The built-in length of 450 mm allows for flexible adaptation to various installation configurations.

Functions and benefits

• Intelligent control: AutoAdapt technology automatically adjusts the pump performance to the system demand, resulting in energy savings and noise reduction. AutoAdapt PLUS function additionally monitors operating conditions and optimizes parameters.
• Communication: The pump supports a number of communication protocols (PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP, LON/LONWorks), enabling integration with building management systems (BMS) and remote monitoring and control. 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals allow for precise adjustment of the pump operation to specific installation requirements.
• High efficiency: The energy efficiency index (EEI) of 0.17 guarantees low electricity consumption.
• Safety: The IPX4 protection class protects the pump against splashing water. Insulation class F ensures safe operation in various environmental conditions.
• Flexibility: The possibility of stepless speed control allows for precise adjustment of the pump performance to current system needs. Constant flow mode (available from production code 1838) maintains constant performance regardless of the head. The FLOW LIMIT function prevents exceeding the nominal flow, eliminating the need for additional throttling valves.
• Durability: The use of high-quality materials and a solid construction ensure long-lasting and reliable operation of the pump. The impeller material is Other - which suggests the use of a material resistant to abrasion and corrosion.

The MAGNA3 pump is an investment in comfort and savings – both for the installer who will appreciate the ease of installation and configuration, and for the end user who will benefit from lower energy bills and quiet operation of the heating or cooling system.
