Grundfos MAGNA1 50-100F (280) Variable Speed Circulator 240V

The Grundfos MAGNA1 50-100F (280) is an A-rated, EuP-ready variable-speed circulator designed for circulating water in heating and domestic hot-water systems where variable flow control and low lifecycle energy use are priorities.

• Variable-speed control with nine light fields for pump-setting indication and three proportional-pressure, three constant-pressure and three fixed-speed curves for flexible system matching.
• Suitable for heating systems, main-pump duties, mixing loops and heating/air-conditioning; external hot-water priority signal forces operation on the max. curve.
• Performance and installation facts: 240V single-phase motor, 50mm flanged connections, 280mm port-to-port dimension, max flow 30 m3/h and max head 10 m.
• Practical benefits from these features include simple selection of pump setting, low noise operation, maintenance-free design, and reduced energy consumption consistent with EuP requirements.

Compact, cast-iron construction and a manufacturer-stated 2-year warranty support durable installation where long operating life and reliable circulation are required.
