ALPHA1 L

The newly designed C-model of the ALPHA1 L pump can be installed in all types of heating systems with variable or constant flow rates. High-efficiency electronically commutated motor (ECM) pumps, such as the ALPHA1 L, are self-steering and automatically adjust the operating parameters to the requirements of the installation. The speed can be adjusted by a low-voltage PWM (pulse width modulated) signal.
