Electronic circulation pump MAGNA3 40-120 F 1x230 V 97924270

Grundfos MAGNA3 circulation pump – an efficient solution for your installation

The Grundfos MAGNA3 40-120 F circulation pump is an advanced device designed to force liquid circulation in heating and air conditioning systems. It is characterized by high energy efficiency, reliability and the ability to adapt to various operating conditions. The wet rotor design and integrated controller ensure quiet operation and minimal operating costs.

Construction and application

MAGNA3 is a canned pump with a synchronous motor with permanent magnets, which translates to higher efficiency compared to traditional asynchronous motors. The pump is equipped with a controller that enables automatic speed regulation, adapting the performance to the current demand for heat or cooling. This ensures that the pump operates optimally, minimizing energy consumption. The pump body is made of gray cast iron (EN-GJL-250 / ASTM A48-250B), which ensures durability and corrosion resistance. The impeller is made of PES 30%GF.

The pump is used in:

• Central heating installations (CH)
• Air conditioning and cooling systems
• Domestic hot water circuits (DHW)
• Solar installations
• Variable flow heating systems

Key features and benefits

• High energy efficiency: Thanks to the permanent magnet motor and intelligent control, the pump consumes a minimal amount of energy. The energy efficiency index (EEI) is 0.18.
• Automatic adaptation: The AUTOADAPT function automatically adjusts the pump's operating parameters to the characteristics of the installation, eliminating the need for manual configuration.
• Versatility: The pump can operate in various modes: constant flow, constant pressure, proportional to pressure and in night mode with reduced rotational speed.
• Communication: Support for communication protocols such as PROFIBUS, RS-485, EtherNet/IP, Modbus RTU and BACnet MS/TP enables integration of the pump with building automation systems (BMS). Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals.
• Low noise operation: The pump design ensures quiet operation, which is particularly important in residential buildings.
• Durability and reliability: Construction from high-quality materials guarantees a long service life of the device. Insulation class F provides resistance to high temperatures. The maximum working pressure is 10 bar and the operating temperature is from -10 to 110°C.
• Easy installation: The innovative clamp allows changing the position of the pump head without having to disassemble the entire structure.

The MAGNA3 pump is an investment in comfort and savings – reliable operation and low operating costs translate into long-term benefits for the user. Using this pump allows you to optimize the operation of the heating or air conditioning installation, ensuring stable temperature conditions with minimal electricity consumption.
