Product Overview
Featuring a cast iron housing grade EN 1561 EN-GJL-200, the Grundfos MAGNA3 32 100 canned-rotor circulator pump provides glandless circulation for hydronic loops and HVAC networks. Internal electronics eliminate shaft seals through a canned-rotor configuration. Primary duties encompass mixing circuits, surface heating, air conditioning, and chiller loops using G 2 inch connections.
Hydraulic performance delivers a maximum head of 10.0 meters and a maximum flow rate of 94.2 L/Min, matching 5.65 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 171 W and current draw of 1.47 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 5.25 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.
