Wet rotor circulation pump MAGNA3 100-40 F 450 1x230V PN10 97924321

High-efficiency and versatile circulation pump

The Grundfos MAGNA3 100-40 F 450 circulation pump is an advanced device designed for circulating water in heating, cooling, and domestic hot water systems. It is characterized by high energy efficiency, intuitive control, and the ability to integrate with various communication systems, making it an ideal solution for both installers and end-users. The pump's closed-impeller design minimizes the risk of failure and ensures quiet operation.

Construction and functionality

MAGNA3 is a circulation pump with a built-in controller and display, allowing for easy configuration and monitoring of its operation. It has a motor speed controller that allows for stepless adjustment of the performance, adapting it to the current needs of the system. It is equipped with a range of communication interfaces – PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP, and LON/LONWorks – which facilitate integration with existing building automation systems. Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals for precise control. The pump body is made of cast iron (GG 25), and the impeller is made of a material other than stainless steel (details in the technical documentation), which ensures durability and corrosion resistance.

Applications and benefits

The MAGNA3 pump finds application in a wide range of installations:

• Heating: central heating systems, underfloor heating, mixing circuits.
• Cooling: air conditioning, district cooling systems.
• Domestic Hot Water: domestic hot water recirculation.
• Industrial Systems: processes requiring precise liquid flow control.

Key advantages:

• High energy efficiency (EEI 0.17): significantly reduces operating costs by optimizing energy consumption.
• Intelligent control: AutoAdapt function automatically adjusts the pump's performance to changing operating conditions, ensuring optimal comfort and energy savings.
• Wide range of communication: possibility of integration with various building automation systems thanks to support for many communication protocols (PROFIBUS, RS-485, etc.).
• Reliability and durability: solid construction with high-quality materials guarantees long-lasting and trouble-free operation.
• Quiet operation: closed-impeller design minimizes noise during pump operation.
• Easy installation and configuration: intuitive display and simple interface facilitate pump configuration and monitoring of its operation.
• FLOW LIMIT function: prevents exceeding the nominal flow, eliminating the need for additional throttling valves.

The Grundfos MAGNA3 pump is an investment in comfort, energy savings, and the reliability of the heating or cooling system. Its advanced features and wide range of applications make it the ideal choice for both new installations and the modernization of existing systems. The maximum working pressure is 10 bar and the motor power is 0.493 kW with a rated current of 2.35 A and a voltage of 230V/50Hz or 60Hz. The connection length is 450 mm and the IPX4 protection class ensures safe use in humid environmental conditions.
