Wet-rotor circulation pump MAGNA3 40-150 F 250 1x230V PN16 97924278

Frameless circulation pump for heating and cooling systems

The Grundfos MAGNA3 40-150 F 250 pump is an advanced device designed for circulating water in heating and cooling systems, both in residential and commercial buildings. Its frameless design 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 optimal operating conditions. Thanks to the integrated controller, the pump can operate in various modes, offering flexibility and precise regulation.

Design and functionality

The MAGNA3 pump has been designed with ease of installation and operation in mind. Made of high-quality cast iron (GG 25), it provides durability and corrosion resistance. It is equipped with a 0.608 kW motor, which allows for a maximum head of 15 meters and a nominal flow rate of 16.03 m³/h. The use of thermal insulation linings (available in single models) minimizes heat loss. The pump has flanged connections (EN 1092-2) on both the inlet and outlet sides, which facilitates integration with the existing installation. The built-in interface allows for easy configuration and monitoring of the pump's operation, as well as connection to building automation systems via communication protocols such as Modbus RTU, BACnet MS/TP or LON/LONWorks.

Advantages for installers and users

• Versatility: The pump is suitable for use in various types of installations – from single-family homes to large multi-family buildings and air conditioning systems with heat exchangers or cooling surfaces.
• Energy saving: Thanks to AutoAdapt technology and the ability to adjust the rotational speed, the pump automatically adjusts its operating parameters to current needs, minimizing electricity consumption (the energy efficiency index EEI is 0.18).
• Comfort of use: The quiet operation of the pump ensures acoustic comfort for building users.
• Easy integration: A wide range of supported communication protocols facilitates the integration of the pump with building automation systems.
• Reliability: The use of high-quality materials and a solid construction guarantee long-lasting and trouble-free operation of the pump.
• Diagnostics: The built-in interface allows monitoring the operating status of the pump and diagnosing any problems.
• Flexible control: The ability to control the pump using analog signals (0-10 V / 2-10 V, 0-20 mA / 4-20 mA) and digital protocols provides flexibility in adapting its operation to specific installation requirements.
• FLOW LIMIT function: Prevents exceeding the maximum nominal flow, eliminating the need for additional throttling valves.
• PT100 / PT1000 / PTC interface signal: Enables integration with temperature sensors for precise regulation of the heating or cooling system.

The MAGNA3 pump is an investment in the comfort, savings and reliability of the heating or cooling system. Its advanced features and solid construction make it the ideal choice for both professional installers and demanding end users.
