Grundfos MAGNA1 100-120F (450) Variable Speed Circulator 240V

The Grundfos MAGNA1 100-120F (450) is an 'A' Rated, EuP‑ready variable speed circulator designed to circulate water in heating and domestic hot‑water systems where flows vary. It delivers up to 65 m3/hr flow and a maximum head of 12 m while operating on 240V single‑phase power, with pumped liquid temperature capability from -10 °C to 110 °C.

• Variable control — selectable proportional‑pressure, constant‑pressure, and fixed‑speed curves (three of each) plus nine status light fields for clear pump‑setting indication.
• System integration — accepts an external hot‑water priority signal to force the pump to the max curve when required (useful in systems with hot‑water priority or solar‑heating setups).
• Durable build — cast iron construction, 450 mm port‑to‑port dimension with 100 mm flanged connections, and a listed weight of 37.0 kg.
• Performance range — motor power and electrical ranges provided: 31.11–1523 W motor size and full load current 0.32–6.73 A.

Simple installation, low noise, maintenance‑free operation and compliance with EuP requirements contribute to low life‑cycle cost. The pump is supplied with a 2‑year manufacturer warranty and is intended for heating, mixing loops, main pump duties and heating/air‑conditioning applications.
