Grundfos MAGNA1 25-120 (180) Variable Speed Circulator 240V

The Grundfos MAGNA1 25-120 (180) is an A‑rated, EuP‑ready variable‑speed circulator for 240V systems, built for circulating water in heating and domestic hot‑water applications. It replaces the UPS25‑100 and is intended for systems with variable flows, mixing loops, and heating and air‑conditioning installations.

• Variable control: nine light fields and selectable pump settings with three proportional‑pressure, three constant‑pressure and three fixed‑speed curves.
• System priority: an external signal can force the pump to the maximum curve for hot‑water priority, useful in solar‑heating or similar setups.
• Durability and operation: maintenance‑free design, low noise level and long life to support low life‑cycle cost.
• Fluid and connections: suitable for circulating water at -10 to 110 °C; MAGNA1 25 series has 180 mm port‑to‑port dimensions with 1 1/2" BSPM screwed connections.
• Electrical: rated for 240V operation (SKU: 97924146).

Choose the MAGNA1 25‑120 (180) where a compact, energy‑efficient circulator with selectable control curves and hot‑water priority capability is required in heating or domestic hot‑water systems.
