Product Overview
Designed with internal electronic controls, the Grundfos MAGNA3 25 120 N canned-rotor circulator pump regulates liquid movement across commercial heating and chilled water loops. Mechanical shaft seals are replaced by a sealed canned-rotor assembly. Plumbing interface connects through G 1 1/2 inch ports in secondary thermal circulation networks.
Hydraulic performance delivers a maximum head of 12.0 meters and a maximum flow rate of 92.7 L/Min, matching 5.56 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 185 W and current draw of 1.56 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.
