Product Overview
The glandless Grundfos MAGNA3 32 120 F circulator pump integrates an air-cooled control panel for secondary thermal circuits and mixing loops. Operating without mechanical shaft seal components, liquid containment relies on an internal rotor can. System hookup connects via DIN DN 32 ports across commercial heating and cooling installations.
Hydraulic performance delivers a maximum head of 12.0 meters and a maximum flow rate of 187.0 L/Min, matching 11.22 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 333 W and current draw of 1.55 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 15.2 kg with a 220 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.
