Product details
The Grundfos Alpha2 is a highly efficient heating circulation pump designed for use in heating systems. It utilizes state-of-the-art ECM technology with a permanent magnet motor that allows for stepless speed adjustment. This feature ensures optimal performance adaptation and energy efficiency. The pump is equipped with an AutoAdapt function that automatically finds the best operating settings. Additionally, it offers an integrated night setback function that further reduces energy consumption. The Alpha2 is suitable for media temperatures ranging from +2 °C to +110 °C and meets the requirements of the Energy Saving Ordinance (EnEV). With a robust gray cast iron housing and a cathodic coating, the pump is particularly corrosion-resistant and durable. An integrated LED display allows for easy monitoring of power consumption or current flow rate.
