Product Overview
The highest head model in the 32 mm threaded range, the Grundfos MAGNA1 32-100 circulator pump is specified for high-resistance heating headers, multi-floor radiant networks, and commercial heat recovery loops. It automatically balances pressure across modulating thermostatic zones.
The 180 mm port-to-port casing is manufactured from EN-GJL-200 cast iron, housing a corrosion-resistant composite impeller 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 4.63 kg.
Operating on a 1-phase 230-240 V 50/60 Hz supply, the ECM motor has a maximum power input (P1) of 8 W to 175 W while electrical input power (P1) draws between 8 W and 175 W at 1.41 A maximum current. Output metrics reach a calculated flow rate of 5.60 m³/h (93 L/Min) with a maximum head of 10 m across G 2 inch threaded ports.
Control options encompass three proportional pressure curves, three constant pressure curves, and three constant speed steps. The pump meets an EEI rating of 0.20, provides Class F winding insulation inside an IPX4D housing, and includes digital input and fault relay contacts.
