GRUNDFOS ALPHA 1L 25-65 ( 130 )



Product description

ALPHA1 L can be used as stand-alone or integrated circulator pump in existing systems as replacement or in new systems with either variable or constant flow rate.
The pump automatically controls the differential pressure by adjusting the pump performance to the actual heating demand without the use of external components, thus avoiding:

• Too high energy consumption
• Irregular control of the system
• Noise in thermostatic valves and similar fittings.

The speed can be controlled by a low-voltage PWM (Pulse Width Modulation) signal.

Features and Benefits: 
• Three constant curves/constant speed curves.
• Radiator heating mode.
• Underfloor heating mode.
• Speed control via a low-voltage PWM (Pulse Width
Modulation) signal profile A (heating). The PWM
signal is a method for generating an analog signal
using a digital source.
• Low EEI (Energy Efficiency Index).
• Deblocking device.
• Maintenance-free.
• Low noise level.
• Very simple installation.
