Product Overview
Engineered for fluid transfer in commercial heating circuits and cooling installations, the Grundfos MAGNA3 25 100 canned-rotor circulator pump operates without mechanical shaft seals. Featuring an integrated control panel, it uses a glandless canned-rotor structure. Applications include mixing loops, heating surfaces, air conditioning, and ground-source loops, via G 1 1/2 inch ports.
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 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 5.11 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.
