Description
The Grundfos ALPHA1 is a high efficiency circulator, designed for pumping liquids in heating and hot water systems. It offers the flexibility to cover 5 or 6m applications with one pump. The ALPHA1 is an economic choice, reaching the highest possible energy savings in contrast to older technology fixed speed pumps. This is acheived by its permanent magnet motor technology, which can be as low as 4 watts – which can be seen on the LCD power display. The variable speed modulating modes allow the pump to match its performance to the system requirements, helping to reduce noise when thermostatic valves are closing. Noise/heat insulation shells are supplied as standard.
