Wet-rotor circulation pump MAGNA3 40-120 F 250 1x230V PN16 97924277

Feature of the product

• High quality
• Stainless steel

Grundfos MAGNA3 40-120 F 250 is an advanced device designed for circulating water in heating and cooling systems, both in residential and commercial buildings. Its design based on a canned motor technology ensures quiet operation and high reliability. The pump is distinguished by its ability to dynamically adjust performance to the current needs of the installation, which translates into energy savings and optimization of operating costs. Thanks to the integrated controller and a wide range of regulation functions, MAGNA3 offers flexibility and precision in flow management.

Design and functionality

The MAGNA3 pump has been designed with ease of installation and maintenance in mind. Made of high-quality cast iron (GG 25), it provides durability and corrosion resistance. It has flanged connections (EN 1092-2) on both the inlet and outlet sides, which facilitates integration with the existing installation. The built-in controller allows for stepless speed control, adjusting the pump's performance to changing operating conditions. This makes it possible to maintain optimal temperature and pressure in the system while minimizing energy consumption.

The pump is equipped with a number of communication interfaces – PROFIBUS, RS-485, EtherNet/IP, Modbus RTU and BACnet MS/TP – which allows it to be integrated with building automation systems (BMS) and remotely monitor its operation. Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals for external control systems. The AutoAdapt function automatically adjusts the pump's operating parameters to the specifics of the installation, ensuring optimal energy efficiency. The AutoAdapt PLUS function additionally monitors changes in the system and reacts to them, maintaining stable operating conditions.

Applications and benefits

The MAGNA3 pump finds application in various heating and cooling systems:

• Central heating installations: ideal for circulating water in radiator systems, underfloor heating and heat exchangers.
• Air conditioning systems: efficient circulation of water in fan coil units, chilled ceilings and cooling surfaces.
• Solar installations: supporting the flow of working fluid in solar collectors.
• Industrial systems: use in technological processes requiring precise flow control of liquids.

Benefits of using the Grundfos MAGNA3 pump:

• Energy savings: thanks to the integrated controller and AutoAdapt/AutoAdapt PLUS functions, the pump adjusts its performance to the current needs of the installation, minimizing electricity consumption.
• Quiet operation: the canned motor design eliminates the risk of cavitation and noise during pump operation.
• High reliability: the solid construction of high-quality materials guarantees long-lasting and trouble-free operation of the device.
• Flexibility: a wide range of regulation functions allows the pump to be adapted to the specifics of various installations.
• Easy integration: a rich set of communication interfaces allows the pump to be integrated with building automation systems (BMS).
• Energy Efficiency Index (EEI): 0.18 – confirms the high energy efficiency of the device in accordance with European standards.
• Remote control capability: thanks to the radio receiver, the pump can communicate with the Grundfos GO application and other MAGNA3 pumps of the same type.

The Grundfos MAGNA3 pump is an investment in the comfort, savings and reliability of a heating or cooling system – both for professionals involved in hydraulic installations and for end-users looking for effective solutions for their home or business.
