Grundfos MAGNA1 D 40-80F (220) Variable Speed Twin Head Circulator 240V

The Grundfos MAGNA1 D 40-80F (220) is an A‑rated, EuP‑ready variable‑speed twin‑head circulator designed for circulating water in heating and domestic hot‑water systems. It delivers up to 26 m3/h flow and up to 8 m head while operating from a 240V 1Ph 50Hz supply, making it suitable where variable flow control and reliable head are required.

• Variable‑speed twin‑head design: provides adaptable flow control for heating circuits, mixing loops and main pump duties.
• Multiple control curves: three proportional‑pressure, three constant‑pressure and three fixed‑speed curves selectable via the nine light fields for clear pump setting indication.
• Hot‑water priority input: external signal forces the pump to the max. curve for applications such as solar‑heating or hot‑water priority systems.
• Robust construction and operating range: cast‑iron body with pumped‑liquid temperature range −10 to 110 °C and 40 mm flanged connections with 220 mm port‑to‑port dimension.
• Low operational noise and low life‑cycle energy consumption; maintenance‑free design reduces routine servicing needs.

Compact yet powerful, this MAGNA1 model balances selectable control modes, wide temperature capability and a high maximum flow to suit a range of heating and domestic hot‑water installations.
