The Grundfos MAGNA1 65-60F (340) is an A‑rated, EuP‑ready variable speed circulator designed for circulating water in heating and domestic hot‑water systems, with easy pump‑setting selection and low life‑cycle cost.
Key features and direct benefits:
Variable‑speed control with nine light fields for pump‑setting indication — lets you match pump performance to system demand.
Three proportional‑pressure, three constant‑pressure and three fixed‑speed curves — provides selection flexibility for different system types.
Suitable for hot‑water priority via external signal — the pump can immediately operate at the maximum curve when signalled (useful in systems such as solar‑heating setups).
Performance and mechanical data: 240V 1Ph 50Hz, max flow 36 m3/hr, max head 6 m, motor output range 23.15–365 W, full load current 0.24–1.64 A.
Construction and dimensions: cast iron body, 65 mm flanged connections, 340 mm port‑to‑port dimension, weight 23.0 kg.
Liquid handling: water; temperature range −10 to 110 °C.
Designed for straightforward installation, low noise operation, and maintenance‑free service life, the MAGNA1 65‑60F is targeted at heating, mixing loop, main pump and HVAC applications where variable flow control and immediate hot‑water prioritisation are required.
