Circulating Pump-Grundfos ALPHA2 15-55 is the standard by which all other variable speed circulating pumps are measured. The ALPHA2 15-55 has a cast iron body with a permanent magnetic motor that allows it reduce energy consumption by over 50% compared to standard circulation pumps. the LC model includes a standard 115 VAC Nema power chord. This product comes with a custom insulated jacket ideal for both heating and cooling. Check valve is also included.
AUTOADAPT measures the system changes and automatically adapts to maximize the energy or to maintain a certain flow rate. Great for multiple zones that open and close at different times as the AUTOADAPT will sense the pressure drop increases the pump speed to compensate for added zones.
