Rather than relying on manual speed selection to balance circulation performance against energy consumption, the Grundfos Alpha2 25-60N uses AUTOADAPT to read system demand and adjust pump speed automatically. It is designed for domestic hot water recirculation loops where continuous adjustment delivers both consistent performance and lower running costs.
Even at its highest duty point the pump draws only 34 W, delivering 32.3 L/Min against 6 m of maximum head, with current consumption self-adjusting between 0.04 A and 0.32 A depending on real-time demand. Rated voltage is 1 x 240 V, and an Energy Efficiency Index of 0.17 reflects the electronically commutated motor's reduced power draw.
An automatic reduced night-time duty mode further limits output during low-demand overnight hours without requiring a separate timer, adjusting based on detected system flow rather than a fixed schedule. The stainless steel pump housing and composite impeller are suited to potable hot water, with liquid temperatures supported from 0°C up to 110°C.
The compact 130 mm port-to-port body suits tighter installation spaces than the longer 180 mm variant, while an IPX4D enclosure rating provides a higher level of ingress protection than the standard IP44 seen on fixed-speed circulators. Class F insulation completes the specification.
