Grundfos MAGNA1 D 32-120F (220) Variable Speed Twin Head Circulator 240V

The Grundfos MAGNA1 D 32-120F (220) is an A-rated, EuP‑ready variable-speed twin-head circulator designed for circulating liquids in heating systems and domestic hot-water systems. It operates on 240V 1Ph 50Hz and supports hot-water priority via an external signal that forces the pump to the maximum curve when required.

• Performance: maximum flow 22 m3/h and maximum head 12 m.
• Temperature and liquid: suitable for water at temperatures from -10 °C to 110 °C.
• Electrical and mechanical: motor power range 16.32–335 W, full load current 0.18–1.5 A, cast-iron construction.
• Connections and dimensions: 32 mm flanged connections, 220 mm port-to-port dimension; overall dimensions 220 mm (h) × 504 mm (w) × 368 mm (d); weight 33.7 kg.
• Controls and efficiency: ‘A’ rated EuP compliance, nine light indicators for pump setting, and selectable curves (three proportional-pressure, three constant-pressure, three fixed-speed) for precise flow control.
• Service and life-cycle: low noise, maintenance-free design and manufacturer’s 2-year warranty.

For heating, mixing loops, and HVAC applications the MAGNA1 D32-120F offers compact flange connections and selectable control curves to match variable flow requirements while keeping energy use low and service needs minimal.
