Circulation pump ALPHA2 GO 25-60 180 220-240V 9H AF0 93074216

Circulation pump for efficient heating and cooling

The Grundfos ALPHA2 GO 25-60 180 circulation pump is a high-performance circulator designed for closed heating and cooling systems in residential buildings. Its design based on a permanent magnet motor and integrated frequency converter ensures significant energy savings, and the low EEI index (0.17) places it among the most energy-efficient devices. This is an ideal solution for both new installations and modernization of existing systems.

Functionality and ease of use

ALPHA2 GO offers a wide range of control options tailored to different needs. The AUTOADAPT function automatically adjusts the pump's performance based on the heat demand, ensuring optimal comfort and minimizing operating costs. In addition, the pump has three operating modes – constant, proportional and curve – each with three settings, allowing for precise adaptation to the specifics of the installation. It is equipped with a clear display showing power consumption, flow rate and any alarms. The function of reducing the temperature after switching on further reduces energy consumption.

Construction and durability

The ALPHA2 GO pump is characterized by a solid construction ensuring long and trouble-free operation. The cast iron housing is electro-corroded to increase corrosion resistance. The impeller made of composite and the ceramic shaft with radial bearings guarantee high durability and reliability. The pump is self-venting, which facilitates its start-up and eliminates the need for manual venting of the installation. Compact dimensions (mounting length 180 mm) make it easy to install even in tight spaces. Dry-running protection protects the pump from damage in the event of a lack of flowing medium.
