Wet rotor circulation pump MAGNA3 40-180 F 250 1x230V PN16 97924279

Flueless circulation pump for heating and cooling systems

The Grundfos MAGNA3 40-180 F 250 pump is an advanced device designed for circulating water in heating and cooling installations. It is characterized by high energy efficiency, flexibility and reliability, and its design allows for dynamic adjustment of performance to the current needs of the system. This is an ideal solution for both residential and commercial buildings.

Design and application

The MAGNA3 pump has been designed with ease of installation and use in mind. Made of high-quality cast iron (GG 25), it provides durability and corrosion resistance. Its flueless design minimizes the risk of the pump becoming blocked by impurities in the medium. The intended use includes underfloor heating systems, installations with heat exchangers (fan coil units, chilled ceilings) and air conditioning systems. Thanks to the ability to adjust the rotational speed, the pump can be optimally adapted to the specifics of the installation, which translates into energy savings and user comfort.

Advantages and benefits

• Energy saving: The integrated controller adjusts the pump's performance to current needs, minimizing energy consumption. The energy efficiency index (EEI) of 0.17 confirms the high efficiency of the device.
• Flexibility: The ability to choose different operating modes (constant pressure, proportional pressure, constant temperature, constant flow) allows for optimal adaptation of the pump to different types of installations. The FLOW LIMIT function prevents exceeding the nominal flow, eliminating the need for additional throttling valves.
• Communication: Support for communication protocols such as PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP and LON/LONWorks enables integration of the pump with building management systems (BMS).
• Reliability: Solid construction using high-quality materials guarantees long-lasting and trouble-free operation. Insulation class F ensures safe use.
• Ease of use: The advanced interface allows for easy configuration and monitoring of the pump's operation. The AutoAdapt function automatically adjusts operating parameters to changing conditions in the system.
• Control signals: Available 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals allow for precise control of the pump from external automation systems.
• High efficiency: The maximum head is 18 meters with a nominal flow rate of 16.04 m³/h. The motor power consumption is 0.609 kW at a voltage of 230V and a frequency of 50/60 Hz.
• Protections: It has a built-in switch and an IPX4 protection class protecting against splashing water.

The MAGNA3 pump is an investment in comfort and savings – a reliable solution for modern heating and cooling systems.
