Wet rotor circulation pump MAGNA3 D 65-100 F 340 1x230V PN6/10 97924492

MAGNA3 circulating pump – an efficient solution for modern installations

Grundfos MAGNA3 65-100 F 340 circulating pump is an advanced device designed for circulating water in heating, air conditioning and domestic hot water systems. It is characterized by high energy efficiency, versatility and the ability to integrate with various control systems. It is an ideal choice for both new and modernized installations, providing optimal operating parameters and reducing operating costs.

Design and application

MAGNA3 is a wet-rotor pump, which means that the pump impeller is completely immersed in liquid. This eliminates the risk of leaks and ensures quiet operation. This design minimizes the need for maintenance, and the bearings are lubricated by the flowing fluid itself. The pump is adapted to work with water at temperatures from -10°C to 110°C and a maximum working pressure of 10 bar. Made of high-quality cast iron (GG 25), which guarantees durability and corrosion resistance. Designed for use in central heating systems, air conditioning, domestic hot water installations, as well as geothermal heat pump and solar collector systems.

Advantages and benefits

• High energy efficiency: An energy efficiency index (EEI) of 0.19 translates into significant energy savings compared to older pump models.
• Versatility: Can be used in a variety of heating, cooling and domestic hot water systems.
• Advanced control: The built-in controller allows for stepless adjustment of the pump speed, adapting the performance to the current needs of the system.
• 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 advanced building management systems (BMS). Additionally, a 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signal is available.
• Easy installation and operation: An intuitive display and the ability to wirelessly connect to the Grundfos GO application make configuration and pump monitoring easier. An innovative clamp allows for easy repositioning of the pump head.
• Durability: The use of high-quality materials – GG 25 cast iron for the housing and carbon fiber reinforced composite for the impeller housing – ensures long-lasting and reliable operation.
• Automatic functions: AUTOADAPT and FLOWADAPT modes automatically adjust the pump operating parameters to the conditions prevailing in the installation, eliminating the need to use throttling valves and optimizing energy consumption.

The MAGNA3 pump is an investment in user comfort and reduced operating costs of the heating or cooling system. Its advanced control and communication functions allow for precise adaptation of performance to current needs, ensuring optimal operating conditions of the installation for many years.
