Circulation pump ALPHA1 25-40 180 220-240V 9H AB0 93074166

Circulation pump for heating systems – reliability and efficiency

The Grundfos ALPHA1 25-40 180 circulation pump is a solution designed for modern and renovated central heating installations. The device combines high efficiency, energy saving and durability, making it an ideal choice for both professional installers and home users. This model works perfectly in systems with radiators and underfloor heating, where stable operation and low operating costs are crucial.

Design and application

ALPHA1 25-40 180 is designed to circulate water in closed heating installations. The compact design (connection spacing 180 mm) makes it easy to install even in limited technical spaces. The motor with ECM technology ensures quiet and stable operation, minimizing electricity consumption. The pump offers three operating modes – proportional pressure, constant pressure and constant speed – allowing precise adjustment to the specifics of a particular installation. The automatic venting function facilitates system start-up, and dry-running protection protects the device from damage.

Advantages of the Grundfos ALPHA1 25-40 180 pump

• Energy saving: the modern EC motor significantly reduces energy consumption compared to traditional circulation pumps.
• Compact dimensions: connection spacing of 180 mm allows installation in tight spaces.
• Versatility: three operating modes allow optimal adaptation to different types of heating installations.
• Reliability: solid construction and high-quality materials ensure long-lasting and trouble-free operation.
• Simple operation: intuitive control panel makes configuration and pump monitoring easy.
• Quiet operation: minimizes noise, which is particularly important in residential buildings.
• Automatic venting: ensures trouble-free start-up of the heating system.
• Dry-running protection: protects the pump from damage in the event of a lack of medium.

The ALPHA1 pump is also characterized by a ceramic shaft and bearings, which minimize wear and extend the life of the device. In the event of the impeller becoming blocked, the motor automatically attempts to start with maximum torque to restore correct pump operation. The built-in diagnostic system facilitates the identification of any problems thanks to error codes displayed on the control panel.

The Grundfos ALPHA1 pump is an investment in comfort and savings, which is appreciated by both professionals and end users looking for a reliable solution for their heating system.
