Product Overview

Providing maximum head in the 25 mm threaded class, the Grundfos MAGNA1 25-120 circulator pump meets the requirements of solar thermal loops, geothermal heat exchangers, and tall hydronic heating risers. Its internal frequency converter adjusts motor speed to match variable heating and cooling demands.

The 180 mm port-to-port casing is manufactured from EN-GJL-200 cast iron, housing a engineered composite impeller and canned rotor motor. Designed for 10 bar operational pressures and fluid temperatures between -10°C and 110°C, the pump has a net weight of 4.39 kg.

The 1-phase 230-240 V ECM motor has a maximum power input (P1) of 8 W to 188 W while electrical input power (P1) operates between 8 W and 188 W with a maximum current of 1.51 A. Peak hydraulic output reaches a flow rate of 5.75 m³/h (96 L/Min) and a maximum head of 12 m across 1 1/2 inch threaded connections.

Nine control curves are selectable directly on the front panel, providing proportional pressure, constant pressure, and fixed speed operation. Features include an EEI rating of 0.20, Class F insulation, an IPX4D housing, and integrated fault relay terminals.
