Product Overview
Combining flanged installation with variable-speed control, the Grundfos MAGNA1 32-40 F circulator pump is suited for commercial fan coil loops, radiant ceiling manifolds, and small chiller circuits. Its integrated frequency converter automatically adjusts speed based on real-time zone valve positions.
The casing is cast from EN-GJL-200 iron with a 220 mm port-to-port dimension and DN 32 DIN flanges, housing a composite impeller and canned rotor motor. Built for 10 bar operating pressure, it accommodates fluid temperatures from -10°C to 110°C, weighing 7.41 kg.
The 1-phase 230-240 V permanent magnet motor has a maximum power input (P1) of 9 W to 73 W while electrical power input (P1) consumes between 9 W and 73 W with a maximum current of 0.59 A. Hydraulic performance achieves a flow rate of 4.24 m³/h (71 L/Min) against a maximum head of 3.391 m through DN 32 flanged pipe connections.
The user interface provides single-touch selection of nine operational modes including proportional pressure, constant pressure, and fixed speed curves. The unit achieves an EEI rating of 0.20, IPX4D ingress protection, Class F insulation, and built-in fault relay terminals.
