Grundfos MAGNA3 Circulation Pump – An Efficient Solution for Your System

The Grundfos MAGNA3 50-100 F 280 circulation pump is an advanced device designed for circulating water in heating, air conditioning, and domestic hot water systems. Its wet-rotor design ensures quiet operation and minimizes the risk of failure, while intelligent control functions allow for optimized energy consumption. It is an ideal choice for both installers looking for reliable equipment and users who value comfort and savings.

Construction and Application

MAGNA3 is a wet-rotor pump, which means the pump impeller is constantly submerged in liquid. This eliminates the risk of pump damage in the event of dry running. Made of high-quality materials – gray cast iron (housing) and PES (impeller) – it guarantees long life and corrosion resistance. Thanks to its compact size and a connection length of 280 mm, the pump easily finds its place even in limited space. It finds application in:

• Heating of commercial and residential buildings
• Air conditioning systems
• Domestic hot water circulation
• District heating and cooling networks
• Industrial heating

Intelligent Control and Communication

The MAGNA3 pump offers a wide range of control and monitoring options. It has a built-in controller with a TFT panel, which enables intuitive configuration of operating parameters. It supports communication protocols such as PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP and LON/LONWorks, allowing integration with building automation systems (BMS). It is also equipped with 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals. Functions such as AUTOADAPT, FLOWADAPT and FLOWLIMIT automatically adjust the pump operating parameters to the current system needs, eliminating the need for throttling valves and optimizing energy consumption.

Performance and Reliability

The MAGNA3 pump is characterized by high hydraulic performance – the maximum flow rate is 16.77 m³/h, and the maximum head is 10 meters. The motor power consumption is 0.403 kW at a rated voltage of 230 V and a frequency of 50/60 Hz. Insulation class F ensures safe operation in various environmental conditions. The energy efficiency index (EEI) of 0.18 confirms the high energy efficiency of the device. The degree of protection IPX4 protects the pump against splashing water.
