The Grundfos ALPHA2 domestic circulator is the most advanced energy efficient domestic circulator of it's kind on the market today. It is the ideal choice for a variety of domestic circulation heating systems, having both variable speed pressure controlled operation, and standard selectable three speed operation.
The ALPHA2 is an 'A' Rated Energy labelled product, achieving the highest possible energy savings under the energy labelling scheme. The reduction in power consumption has been achieved by using the latest permanent magnet motor technology. Using pressure controlled operation power consumption can be reduced to as low as 5 watts.
The unique AUTOADAPT feature allows the pump to match it's performance to the system requirements, helping to reduce noise when thermostatic valves are closing down.
The ALPHA2 models are simple to install as new or replacement pumps, and are 130mm between ports.
