High-Quality Circulatory Pumps for Hot & Cold Water
ALPHA2 is the latest and most innovative member of the Grundfos family of high-quality circulators.
With ALPHA2, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting, AUTOADAPT. ALPHA2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand.
- Flow, Q: max. 10 m3/h
- Head, H: max. 12 m
- Liquid temperature: +15°C to +110°C
- Operatiing pressure: max. 10 bar.
The Grundfos ALPHA2 is designed for circulating liquids in heating systems. Pumps with stainless steel pump housings can also be used in domestic hot-water systems.
The Grundfos ALPHA2 is suitable for:
- Circulation of hot or cold water in heating systems, domestic hot water systems, cooling and air-conditioning systems
- Systems with constant or varying flows where it is desirable to optimise the pump duty point
- Systems with a varying flow-pipe temperatures
- Systems where night setback is required.
