Grundfos MAGNA1 D 40-100F (220) Variable Speed Twin Head Circulator 240V

The Grundfos MAGNA1 D 40-100F (220) is an A-rated, EuP-ready variable-speed twin-head circulator designed to circulate water in heating systems and domestic hot-water systems using a 240V supply.

• Variable-speed twin-head circulator with easy selection of pump setting and nine light fields that indicate the chosen setting.
• Three proportional-pressure curves, three constant-pressure curves and three fixed-speed curves provide selectable control for variable-flow heating and mixing loops.
• Designed for low energy consumption and low noise; the pump requires no routine maintenance and is presented with a 2-year manufacturer warranty.
• Suitable for hot-water priority integration: an external signal can force the pump to operate at the maximum curve (useful for applications such as solar-heating systems).
• Key technical details: pumped liquid — water; liquid temperature range -10 to 110 °C; port-to-port dimension 220 mm with 40 mm flanged connections; max flow 29 m3/h; max head 10 m.

Construction and electrical data include cast-iron body, motor power range 18.05–383 W, full-load current 0.2–1.7 A, and single-phase 240 V 50 Hz operation. Dimensions and mass: 220 mm (h) × 504 mm (w) × 379 mm (d), weight 36.2 kg. GTIN: 5710626494583.
