Grundfos MAGNA1 25-40 (180) Variable Speed Circulator 240V

The Grundfos MAGNA1 25-40 (180) is an A‑rated, EuP‑ready variable‑speed circulator (240V, item 99221216) designed to circulate water in heating and domestic hot‑water systems where flow varies. It offers selectable pump curves and an external signal input for hot‑water priority, so the pump can run to the maximum curve when required.

• Applications: heating systems, main pump, mixing loops, heating and air‑conditioning.
• Control options: three proportional‑pressure, three constant‑pressure and three fixed‑speed curves selectable via nine light fields for pump‑setting indication.
• Performance and installation facts: MAGNA1 25 series has 180 mm port‑to‑port dimension with 1 1/2" BSPM screwed connections; pumped liquid temperature range −10 to 110 °C.
• Operational benefits: low noise level, maintenance‑free design and low life‑cycle energy consumption (complies with EuP requirements).

Compact and versatile, this MAGNA1 circulator is intended for systems that need reliable variable‑speed pumping with straightforward selection of operating modes and hot‑water priority capability.
