Grundfos MAGNA1 25-60 (180) Variable Speed Circulator 240V

Energy‑aware variable‑speed circulator for heating and DHW systems. The Grundfos MAGNA1 25-60 (180) is an A‑rated, EuP‑ready variable‑speed circulator for circulating water in heating systems, domestic hot‑water setups and mixing loops. It operates on 240V and is designed for low life‑cycle cost with simple selection of pump setting and maintenance‑free operation.

• Variable operation modes: three proportional‑pressure, three constant‑pressure and three fixed‑speed curves provide flexibility to match system demand.
• Quick status and setting: nine light fields indicate pump setting for straightforward commissioning.
• System compatibility: suitable for heating, main pump duties, mixing loops and heating/air‑conditioning applications; external hot‑water priority signal can force the pump to the maximum curve for systems such as solar heating.
• Key service facts: pumped liquid is water; liquid temperature range −10 to 110 °C; port‑to‑port dimension 180 mm with 1 1/2" BSPM screwed connections.

The MAGNA1 25‑series combines low energy consumption (compliant with EuP) and low noise in a compact, easy‑set circulator intended for variable‑flow heating and hot‑water systems.
