Stainless steel circulator pump designed for pumping domestic hot water in households. The AUTOADAPT function continuously adjusts the pump settings according to the system's requirements. Installing the ALPHA2 pump significantly reduces energy consumption, lowers noise from thermostatic radiator valves and similar devices, and improves system control.
