Grundfos MAGNA1 D 32-100 (180) Variable Speed Twin Head Circulator 240V

Purpose-built for circulating hot-water in heating and domestic hot-water systems, the Grundfos MAGNA1 D 32-100 (180) is an A-rated, EuP-ready variable-speed twin-head circulator designed to lower running costs while delivering regulated flow and pressure.

• Variable-speed control with nine light fields for pump-setting indication and three proportional, three constant and three fixed-speed curves — for predictable regulation in systems with changing demand.
• Suitable for heating systems, main pumps, mixing loops and heating & air-conditioning; supports hot-water priority via an external signal that forces the pump to the max curve (useful in solar-heating setups).
• Technical highlights: 240V 1Ph 50Hz supply; motor power 8–175 W; full-load current 0.08–1.41 A; max flow 15 m3/h; max head 10.5 m.
• Robust, service-free operation: cast-iron construction, low noise, maintenance-free design and a 2-year manufacturer warranty.
• Installation facts: 180 mm port-to-port dimension with 2" BSPM screwed connections; pumped-liquid temperature range −10 to 110 °C.

Compact and specified for variable-flow heating applications, this MAGNA1 model combines controlled performance with the plumbing and electrical specifications needed for straightforward integration into existing systems.
