Peace of Mind
Product Overview
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 approx. 56.6 L/Min with a maximum head up to 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.
FEATURES
- AUTOADAPT function reads system behaviour and adjusts pump speed continuously without manual intervention
- Automatic reduced night-time duty mode lowers output during low-demand overnight periods, detected from system flow
- Electronically commutated permanent magnet motor achieves an Energy Efficiency Index of 0.17
- Current consumption self-adjusts from 0.04 A to 0.32 A as the pump responds to changing system demand
- Stainless steel housing with potable water approval and liquid temperature support from 0°C to 110°C
- Composite impeller construction offers corrosion resistance in potable water service
- IPX4D enclosure rating provides ingress protection against splashing water and dust
- Class F insulation supports continuous operation within the pump's rated temperature range

What motor power rating and running current power this pump?
Connecting across 240 V lines, the Grundfos Alpha2 25-60N draws approximately 0.32 Amps with an efficient 0.034 kW motor.
How deep can this pump be submerged underwater?
Fluid media ranging up to 0°C to 110°C can be circulated through the Alpha2 25-60N without thermal breakdown.
What maximum vertical elevation head can this pump achieve?
To overcome vertical elevation resistance, the Alpha2-25-60N develops a maximum pumping head of approximately up to 6 m.
How much water volume can this pump displace through its outlet?
At full operating capacity, the Alpha2 25 60N moves approx. 56.6 L/Min to keep liquid levels controlled during peak inflow.
What materials make this pump durable against corrosion and wear?
Structural defense on the Alpha2/25/60N is provided by a rugged Stainless Steel casing designed to withstand heavy mechanical stress.
