Electronic circulation pump MAGNA3 65-120 F 1x230V PN6/10 97924298

Grundfos MAGNA3 electronic circulation pump – comfort and efficiency in your system

The Grundfos MAGNA3 65-120 F electronic circulation pump is an advanced solution designed to force liquid circulation in heating, air conditioning and domestic hot water systems. It is characterized by high energy efficiency, versatility and the ability to integrate with modern building management systems. It is an ideal choice for both new and modernized installations.

Design and functionality

MAGNA3 is a wet rotor pump, which means that the pump impeller is completely immersed in the liquid. This eliminates the risk of leaks and ensures quiet operation. The pump motor is based on permanent magnet technology, which translates into higher efficiency compared to traditional asynchronous motors. The built-in controller and frequency converter enable smooth speed control, adapting the pump's performance to current demand. The pump has flanged inlet and outlet connections (EN 1092-2) and is designed to work with media at temperatures from -10 to 110°C. The pump body is made of cast iron GG 25 (GJL-250), which ensures durability and corrosion resistance.

Communication and control

One of the key advantages of the MAGNA3 pump is its extensive communication functionality. It supports PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP, LON/LONWorks protocols and has 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals. This allows the pump to be easily integrated with building automation systems (BMS) and remotely controlled. Additionally, the pump has a potential-free changeover contact and the ability to communicate via Bluetooth – although the lack of support for WLAN 802.11 standards or CAN/CANOpen, PROFINET IO or Modbus TCP protocols limits its capabilities in some advanced systems. The AUTOADAPT function automatically adjusts the pump's operating parameters to the conditions prevailing in the installation, minimizing energy consumption and ensuring optimal user comfort.

Applications

The Grundfos MAGNA3 65-120 F pump is used in:

• Central heating systems (CH)
• Air conditioning and cooling systems
• Domestic hot water (DHW) systems
• Mixing loops
• Ground source heat pump systems
• Solar heating systems
• Industrial installations requiring precise flow control

Thanks to its versatility and reliability, this pump is an excellent choice for both installers and end users looking for an efficient and energy-saving solution for forcing liquid circulation in their heating or air conditioning system. The pump achieves a maximum flow rate of 25.76 m³/h with a head of up to 12 meters, and its motor consumes 0.763 kW with a rated current of 3.45 A. The IPX4 degree of protection ensures safe operation in humid conditions.
