Wet rotor circulation pump MAGNA3 D 100-40 F 450 1x230V PN10 97924516

Flangeless circulation pump for heating and cooling systems

The Grundfos MAGNA3 D 100-40 F 450 circulation pump is a high-performance device designed for circulating water in central heating and cooling installations. It is characterized by energy efficiency, quiet operation and the ability to adapt to changing operating conditions. It is an ideal solution for both residential and commercial buildings where a reliable and efficient circulation pump is required. Thanks to the AutoAdapt technology, the pump automatically adjusts its operating parameters, optimizing energy consumption and ensuring user comfort.

Design and functionality

The MAGNA3 pump has been designed with ease of installation and operation in mind. It is equipped with an integrated controller that enables stepless speed control, adapting the pump's performance to the current demand for heat or cooling. The pump body made of cast iron GG 25 (GJL-250) ensures durability and corrosion resistance. The pump switch (other type) and insulation class F guarantee safe and long-lasting operation. The electrical connection is made using terminals, and the rated voltage is 230V. The pump has flanged inlet and outlet connections with a pressure class of PN10.

Communication and control

One of the key features of the MAGNA3 pump is its extensive communication functionality. It supports PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP and LON/LONWorks protocols, enabling integration with modern building management systems (BMS). Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals for remote control and monitoring. The lack of support for wireless communication Bluetooth, WLAN or PROFINET IO or BACnet IP protocols does not limit its functionality in most typical applications. The built-in interface prepared for communication facilitates configuration and diagnostics of the device.

Performance and operating parameters

The MAGNA3 D 100-40 F 450 pump offers a maximum head of 4 meters and a nominal flow rate of 23.83 m³/h at a head of 49.98 kPa. The motor power consumption (P1) is 0.53 kW, and the energy efficiency index (EEI) is only 0.17 – which demonstrates the high energy efficiency of the device. The pump speed is 2490 rpm, and its rated current is 2.41 A. The pump operates at an ambient temperature of 0 to 40°C and a medium temperature of -10 to 110°C. The maximum working pressure is 10 bar.
