Product Overview
Capable of developing 6.353 m of head, the Grundfos MAGNA1 25-100 circulator pump serves multi-zone heating systems, long distribution runs, and high-resistance fan coil circuits. It automatically modulates hydraulic performance to deliver balanced circulation as zone valves cycle.
A cast iron EN-GJL-200 housing with a 180 mm face-to-face dimension encloses a composite impeller and maintenance-free canned rotor motor. Rated for 10 bar working pressure and liquid temperatures from -10°C to 110°C, the complete unit weighs 4.41 kg.
The single-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 176 W and operates from 9 W to a maximum electrical power input (P1) of 176 W at 1.42 A. Hydraulic delivery achieves a flow rate of 5.68 m³/h (95 L/Min) with a maximum head of 10 m through 1 1/2 inch threaded connections.
The user interface provides single-button setup across nine operational modes covering proportional, constant pressure, and fixed speed curves. The motor features Class F insulation, IPX4D ingress protection, an EEI of 0.20, and built-in fault signal monitoring.
