ALPHA2 is a complete range of standalone* circulators. More than 3 million ALPHA2s have rolled off our production lines since its introduction in 2007. The ALPHA2 L variant features integrated differential-pressure control, enabling adjustment of pump performance to the actual system requirements. The installation of a GRUNDFOS ALPHA2 L pump will reduce the power consumption considerably, reduce noise from thermostatic valves and similar fittings, and improve the control of the system.
Characteristic Features:
- High Efficiency circulator for standalone applications based on a permanent-magnet motor/compact-rotor technology
- According Ecodesign requirement January, 2013; EEI ≤ 0.23
- Internally self-controlled circulator
- Integrated differential-pressure control enabling adjustment of pump performance to the actual system requirements.
- 5 Configuration Options:
highest proportional pressure curve (default),
lowest proportional pressure curve
lowest constant pressure curve
highest constant pressure curve
constant curve speed I, II and III
- ALPHA2 L can run on as little as 5 W
Benefits:
- Enhance System Efficiency
Due to the ALPHA2 L, control is affected by adapting the differential pressure to the flow. (proportional- and constant-pressure control). Contrary to an uncontrolled pump, the proportional-pressure-controlled GRUNDFOS ALPHA2 L reduces the differential pressure as a result of falling heating demand.
- Compact Design
Small and easy accessible compact design with control integrated in pump
- High reliability
Ceramic bearing shaft.
The ALPHA2 L comes equipped with ceramic bearing shafts for a long and trouble-free lifetime. The ceramic material is extremely durable and will not wear.
De-blocking system.
Electronic de-blocking that maintains the maximum starting torque up to 25 Ncm. Field and lab tested product quality
