Grundfos MAGNA1 40-100F (220) Variable Speed Circulator 240V

The Grundfos MAGNA1 40-100F (220) is a variable-speed circulator designed for circulating water in heating and domestic hot-water systems. It replaces the UPS 40-100F and provides selectable pump settings with three proportional-pressure, three constant-pressure and three fixed-speed curves, plus nine light fields that indicate the chosen setting.

• Applications: heating systems, main pump, mixing loops, heating and air-conditioning; suitable for systems with hot-water priority.
• Performance: maximum flow 23 m3/h and maximum head 10 m; motor output range listed as 17.03–370 W with full-load current 0.19–1.65 A.
• Design and installation: 220 mm port-to-port dimensions with 40 mm flanged connections; cast-iron construction and maintenance-free operation.
• Electrical and temperature: 240 V 1Ph 50 Hz supply; pumped liquid temperature range −10 to 110 °C.

Concrete, pump-specific controls and EuP-ready energy performance make the MAGNA1 40-100F suitable where variable flow and reliable hot-water priority are required. The unit’s listed weight (18.2 kg) and compact flanged layout support retrofit and replacement installations where the UPS 40-100F was previously used.
