Product Overview
For HVAC water circulation and climate control circuits, the Grundfos MAGNA3 25 100 N canned-rotor unit utilizes a glandless pump design with G 1 1/2 inch 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 10.0 meters and a maximum flow rate of 90.5 L/Min, matching 5.43 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 153 W and current draw of 1.33 Amps. Maximum system operating pressure is rated at 10 bar.
Housing construction features a stainless steel casing grade EN 1.4308 ASTM A351-CF8 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 5.12 kg with a 180 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 premium stainless steel material prevent corrosion in sanitary water loops?
Mechanical fluid circulation within the MAGNA3 25-100-N utilizes a Stainless Steel housing with composite impeller engineered for potable water hygiene and corrosion defense.
What electrical voltage and motor kilowatt power consumption are specified for this unit?
Electrical drive engineering on the Grundfos MAGNA3 25-100-N incorporates a motor delivering 0.15 kW (150 W) powered by 240 V drawing a rated current of 1.33 Amps.
What operating pressure limit in bar and fluid temperature conditions govern this sanitary circulator?
Installed into domestic water distribution loops, the MAGNA3-25-100-N tolerates working pressures up to 10 bar in fluids from -10°C to +110°C.
Under full hydraulic load, what dynamic head lift does this stainless unit deliver?
Hydraulic elevation force delivered by the Grundfos MAGNA3 25 100 N reaches a maximum dynamic head of approximately 10 m.
What peak delivery flow rate does this stainless circulator discharge through its connection port?
Managing high-volume sanitary duty, the MAGNA3_25_100_N maintains a maximum delivery flow rate of approximately 90.5 L/Min across 180 mm port-to-port G 1 1/2 inch threaded connections.
