Product Overview
Developing 5.383 m of head at flow rates nearing 300 L/Min, the Grundfos MAGNA1 50-100 F circulator pump is specified for large commercial HVAC plants, central heating headers, and district cooling loops. It automatically balances pressure across extensive multi-zone building distributions.
The 280 mm port-to-port casing is manufactured from EN-GJL-200 cast iron, housing a composite impeller, stainless rotor can, and air-cooled electronic power module. Rated for 10 bar working pressure, it accommodates fluid temperatures from -10°C to 110°C with a net weight of 17.9 kg.
Operating on a 1-phase 230-240 V 50/60 Hz supply, the ECM motor has a maximum power input (P1) of 21 W to 425 W while electrical input power (P1) draws between 21 W and 425 W at 1.90 A maximum current. Output metrics reach a calculated flow rate of 17.73 m³/h (296 L/Min) with a maximum head of 10 m across DN 50 DIN flanged ports.
Control options encompass three proportional pressure curves, three constant pressure curves, and three constant speed steps. The pump meets an EEI rating of 0.19, provides Class F winding insulation inside an IPX4D housing, and includes digital input and fault relay contacts.
