Grundfos MAGNA1 D 40-60F (220) Variable Speed Twin Head Circulator 240V

The Grundfos MAGNA1 D 40-60F (220) is an A-rated, EuP-ready variable-speed twin-head circulator designed for circulating water in heating and domestic hot-water systems. It supports variable flows and hot-water priority via an external signal to force pump operation to the maximum curve, making it suitable for heating systems, mixing loops and heating & air-conditioning applications.

• Variable-speed twin-head circulator with easy selection of pump setting and nine light fields indicating pump status.
• Three proportional-pressure curves, three constant-pressure curves and three fixed-speed curves for matching system demands.
• Low life-cycle energy use and low noise level; maintenance-free design for long service life.
• Key specifications: 240V 1Ph 50Hz supply, max flow 23 m3/h, max head 6 m, pumped liquid temperature range -10 to 110 °C.
• Physical and electrical data: cast-iron construction, port-to-port 220 mm, flanged connections 40 mm, weight 20.0 kg, motor power range 12–194 W, full-load current 0.11–1.56 A.

Supplied as the MAGNA1 D40 series with potential spacer-kit requirement when replacing older MAGNA or UPS/D models due to port-to-port differences. The pump comes from Grundfos and is offered with a 2-year manufacturer’s warranty.
