Grundfos MAGNA1 80-100F (360) Variable Speed Circulator 240V

The Grundfos MAGNA1 80-100F (360) is an A-rated, EuP-ready variable-speed circulator designed for circulating water in heating and domestic hot-water systems. It offers selectable pressure and speed curves and is intended for systems with variable flows or hot-water priority, where an external signal can force operation at the maximum curve.

• Performance: up to 55 m3/hr maximum flow and 10 m maximum head, suitable for main pumps, mixing loops, heating and air-conditioning circuits.
• Dimensions & connections: 360 mm port-to-port and 80 mm flanged connections (MAGNA1 80 range).
• Electrical: 240 V, 1-phase, 50 Hz supply; motor power and current range listed as 30.7–1014 W and 0.31–4.45 A respectively.
• Design benefits: A-rated energy performance (EuP compliant), low noise, maintenance-free operation, and multiple selectable curves including proportional-pressure, constant-pressure, and fixed-speed options.

Constructed with a cast-iron body and specified for water temperatures from -10 °C to 110 °C, the MAGNA1 80-100F is presented as a long-life, low life-cycle-cost circulator for professional heating and hot-water applications.
