MAGNA3 65-80 F 340 1x230V PN6/10 wet-rotor circulation pump 97924296

Circulation pump for efficient heating and cooling

The Grundfos MAGNA3 65-80 F circulation pump is an advanced solution for heating and cooling systems, designed to optimize energy consumption and ensure user comfort. It utilizes permanent magnet technology and electronic speed control, which translates to quiet operation and long service life. It is a reliable component of the system that adapts to current needs, minimizing operating costs.

Design and functionality

The MAGNA3 pump is characterized by a solid construction with a housing made of cast iron GG 25 (GJL-250), which ensures corrosion resistance and long-term reliability. It is equipped with a motor speed controller, enabling smooth performance adjustment. Flanged connections (EN 1092-2) on the inlet and outlet sides facilitate integration with the existing installation. The connection length is 340 mm, which should be taken into account when planning the installation. The maximum working pressure of the pump is 10 bar, and the average continuous operating temperature is in the range of -10 to 110°C.

Communication and control

One of the key advantages of the MAGNA3 pump is its advanced communication system. It supports protocols such as Modbus RTU, PROFIBUS, LON/LONWorks, BACnet MS/TP and EtherNet/IP, allowing for easy integration with building automation systems (BMS). Additionally, it has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals for precise performance control. The built-in interface is prepared for communication, and the presence of a potential-free changeover contact increases the flexibility of applications. Remote monitoring and control allow for optimization of pump operation and quick response to potential failures.
