Grundfos MAGNA1 D 32-100F (220) Variable Speed Twin Head Circulator 240V

The Grundfos MAGNA1 D 32-100F is a variable-speed, twin-head circulator engineered for circulating water in heating and domestic hot-water systems. It offers easy selection of pump settings and is EuP-ready with an 'A' energy rating, delivering low energy consumption and quiet operation for continuous system use.

• Variable-speed twin-head design with 220 mm port-to-port dimensions and 32 mm flanged connections — suited to main pumps, mixing loops and heating/air-conditioning circuits.
• Max flow 15 m3/h and max head 10.5 m, supporting a broad range of system requirements while the motor range (8–175 W) and full-load current (0.08–1.41 A) reflect low electrical demand.
• Cast-iron construction, maintenance-free operation and low noise level for long service life in typical heating-system environments.
• Operational features: nine light fields for pump-setting indication, three proportional-pressure, three constant-pressure and three fixed-speed curves; external signal can force max curve for hot-water priority.
• Pumped liquid: water. Liquid temperature range: -10 to 110 °C. Voltage: 240 V, 1Ph, 50 Hz.

Compact but capable, the MAGNA1 D 32-100F combines straightforward controls and documented hydraulic performance to meet demanding circulating tasks in commercial or residential heating and hot-water systems.
