    Designed with a 32 mm bore and 2-inch threaded connections, the Grundfos MAGNA1 32-40 circulator pump provides energy-efficient variable circulation for fan coil loops, radiant ceiling systems, and small chiller circuits. It regulates motor speed dynamically to match real-time heating and cooling demands.

    An EN-GJL-200 cast iron pump body with a 180 mm port-to-port dimension encases a composite impeller and maintenance-free canned rotor. Built for 10 bar working pressure, it handles liquid temperatures ranging from -10°C to 110°C, with a net mass of 4.61 kg.

    The single-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 73 W while electrical power input (P1) modulates between 9 W and 73 W with a maximum current draw 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 G 2 inch threaded ports.

    The interface allows selection between three proportional pressure curves, three constant pressure curves, and three fixed speeds. The unit meets an EEI rating of 0.20, features Class F insulation with an IPX4D enclosure, and includes digital run/stop and fault relay contacts.

    FEATURES

    • Permanent magnet ECM motor with integrated inverter achieves an EEI of 0.20
