The Grundfos MAGNA3 80-120 F circulator pump offers a smart solution for all heating, ventilation and cooling systems. The energy consumption of the MAGNA3 is well below the target level of the energy efficiency directives. The AUTOADAPT function pre-installed in the MAGNA3 pumps enables easy commissioning and optimizes the pump's operation, in addition, the FLOWLIMIT in the pump limits the maximum flow and makes valves unnecessary.
MAGNA3 measures and controls the system's heat energy consumption with a built-in heat energy meter. The Grundfos GO Remote mobile app allows you to control the pump even in difficult locations. The F models are flange-mounted. Grundfos MAGNA circulators are suitable for hot water circulation or as part of heating and cooling systems in households, commercial premises and light industrial use.

Communication MAGNA3 enables communication via:
- Grundfos GO wireless remote control
- Fieldbus communication via CIM modules
- Digital inputs
- Relay outputs
- Analog input (more than pump function, heat energy meter)
Other information:
- MAGNA3 is a single-stage pump
- Motor and electronic controller The MAGNA3 uses a 4-pole permanent magnet motor (PM motor). This type of motor has the advantage of being more efficient than a squirrel-cage motor.
- The pump speed is controlled by an integrated frequency converter. A differential pressure sensor and a temperature sensor are included in the pump.
