Product Overview
For HVAC water circulation and climate control circuits, the Grundfos MAGNA3 40 120 F canned-rotor unit utilizes a glandless pump design with DIN DN 40 connection ports. The integrated control box manages operational settings without external shaft seals. Fluid circulation serves commercial heating loops, chilled water networks, and ground-source heat pump exchangers.
Hydraulic performance delivers a maximum head of 12.0 meters and a maximum flow rate of 235.7 L/Min, matching 14.14 m3/h. Powered by a permanent-magnet motor, the unit operates on a 240 V single-phase supply at 50/60 Hz, with power input P1 of 427 W and current draw of 1.96 Amps. Maximum system operating pressure is rated at 10 bar.
Housing construction features a cast iron casing grade EN 1561 EN-GJL-200 enclosing a composite impeller. Internal components incorporate a carbon-fibre rotor can, stainless steel rotor cladding, and bearing plate, running on ceramic bearings. Net weight is 16 kg with a 250 mm port length, handling liquid temperatures -10 to 110 °C.
Control features include AUTOADAPT and FLOWADAPT operating modes with integrated differential pressure and temperature sensors. Wireless communication connects via Bluetooth to Grundfos GO Remote software for diagnostics. External interfaces provide two digital inputs, two signal relays, and a 0-10V analog input.

How does the metallurgical casing design defend this commercial pump against particulate wear?
Manufacturing standards for the MAGNA3 40-120-F specify a Cast Iron housing with composite impeller providing exceptional defense against thermal stresses.
What supply voltage and motor power kilowatt rating are designated for this cast iron unit?
Functioning on building electrical distribution, the Grundfos MAGNA3 40-120-F employs a motor rated at 0.43 kW (430 W) running on 240 V drawing a rated current of 1.96 Amps.
How much system operating pressure in bar and liquid temperature can this circulator sustain?
Chilled and hot water guidelines establish that the MAGNA3-40-120-F sustains system pressures up to 10 bar across liquid temperatures from -10°C to +110°C.
Under peak operation, what dynamic head and fluid lift elevation does this circulator develop?
Elevating hydronic fluid through circulation loops, the Grundfos MAGNA3 40 120 F reaches a peak dynamic head rating of approximately 12 m.
What delivery flow rate and connection flange diameter are engineered into this heating unit?
Supplying multi-zone hydronic loops, the MAGNA3_40_120_F maintains a maximum delivery flow rate of approximately 235.7 L/Min through DN 40 flanged connections.
