Wet rotor circulation pump MAGNA3 65-100 F 340 1x230V PN6/10 97924297

Grundfos MAGNA3 circulation pump – an efficient solution for your system

The Grundfos MAGNA3 65-100 F 340 circulation 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 built-in communication functions, making it an ideal choice for both new and modernized installations. The wet rotor design minimizes the risk of failure and ensures quiet operation.

Construction and application

MAGNA3 is a canned pump, which means that the pump impeller and motor form an integrated unit without a shaft seal. This solution eliminates potential leaks and extends the life of the device. The bearings are lubricated by the pumped liquid, which further increases reliability. The pump has a built-in controller integrated in the control box and an intuitive TFT display to facilitate configuration and monitoring. Thanks to the ability to communicate with the Grundfos GO application, access to data and remote control is extremely simple.

The pump is used in:

• Mixing loops
• Heating installations
• Air conditioning and cooling systems
• Domestic hot water installations
• Systems with a geothermal heat pump
• Solar heating systems

Advantages and benefits

• High energy efficiency: Thanks to the use of a synchronous motor with permanent magnets (PM) and AUTOADAPT and FLOWADAPT technologies, the pump minimizes energy consumption. The energy efficiency index (EEI) is 0.17, which places it among the most energy-saving devices.
• Versatility: A wide range of operating parameters allows the pump to be adapted to different types of installations and operating conditions.
• Advanced control functions: Built-in AUTOADAPT and FLOWADAPT modes automatically adjust the pump's performance to the current system needs, eliminating the need for throttling valves and optimizing operating costs.
• Communication: Support for PROFIBUS, RS-485, EtherNet/IP, Modbus RTU and BACnet MS/TP protocols enables integration of the pump with building automation systems (BMS). Additionally, Bluetooth communication is available for remote monitoring via a mobile application.
• Durability and reliability: Construction from high-quality materials (gray cast iron GG 25 for the pump body) and the absence of a shaft seal ensure a long service life and minimize the risk of failure.
• Easy installation and operation: The innovative clamp facilitates changing the position of the pump head, and the intuitive control panel simplifies device configuration.

The MAGNA3 65-100 F 340 pump is characterized by a maximum flow rate of 23.65 m³/h and a maximum head of 10 meters. It operates at a voltage of 230V (1 phase) with a power consumption of 0.6 kW and a rated current of 2.74 A. The connection length is 340 mm and the IPX4 protection class provides resistance to splashing water. Flanged connections with a diameter of DN65 (EN 1092-2) facilitate installation in existing installations.
