Grundfos MAGNA1 D 32-40F (220) Variable Speed Twin Head Circulator 240V

The Grundfos MAGNA1 D 32-40F (220) is a variable-speed twin-head circulator designed for circulating water in heating and domestic hot-water systems, offering A-rated EuP-ready efficiency and low life-cycle energy use.

• Variable-speed operation with nine light-field indicators for easy selection of pump setting, including three proportional-pressure, three constant-pressure and three fixed-speed curves.
• Suitable for heating systems, main pump duties, mixing loops and heating & air-conditioning; can accept an external signal to force maximum curve operation (useful for hot-water priority or solar-heating systems).
• Performance and electrical data: 240 V 1Ph 50 Hz, motor power range 9–73 W, full-load current 0.09–0.59 A, max flow 11.5 m3/h and max head 4 m.
• Construction and service: cast-iron pump body, maintenance-free design, low noise level and a manufacturer warranty of 2 years.

The unit has 220 mm port-to-port dimensions with 32 mm flanged connections and handles pumped liquid temperatures from -10 °C to 110 °C. Its compact dimensions (220 mm × 400 mm × 211 mm) and 15.7 kg weight make it straightforward to install where a flanged, variable-speed circulator is required.
