Circulator pump ALPHA2 25-40 130 - GRUNDFOS : 99411143

The AUTOADAPT function automatically finds the best setpoint value, thereby reducing energy consumption and adjustment time. A display shows the real power absorbed in Watts or the real flow in m3/h for regulation purposes.

Night mode available if the installation manages it, in order to optimise energy savings.
Simple selection between three constant pressure curves, three proportional pressure curves or three fixed speeds at the touch of a single button.
Simple, fast and safe electrical connection due to the ALPHA connector.
ALPHA2 is suitable for cold water systems, potable water approval. Very good flexibility of applications.
Electrolytic coated pump body.
No external protection of the motor is required. Reduced installation time and costs.
Improved starting system that allows the circulator pump to start even under difficult conditions.
Protection against dry running. Protects the circulator pump at start-up and during daily operation if there is no water in the installation.
Summer mode. Energy saving during the summer - consumption < 0.8W and ensures safe start-up when starting up the heating
