Circulation pump – an efficient solution for your heating system

The ALPHA2 25-80 N 180 circulation pump is an advanced device designed for circulating water in central heating and domestic hot water systems. It utilizes innovative technologies that ensure high energy efficiency and user comfort. The construction made of high-quality stainless steel guarantees long-lasting and reliable operation even in demanding conditions.

Construction and application

The ALPHA2 pump is designed for easy installation and use. Its compact size (built-in length 180 mm) allows for installation in limited spaces. Threaded connections with a diameter of 1 1/2 inch (40) compliant with EN 1092-2 standard facilitate integration with the existing installation. Made of durable stainless steel (grade 304 – 1.4308) provides corrosion resistance and longevity. The pump is adapted to work in ambient temperature from 0 to 40°C and working medium up to 110°C, which makes it a universal solution for various applications. The maximum working pressure is 10 bar, and the maximum head is 8 meters, with a nominal flow rate of 2.14 m³/h.

Advantages and benefits

• High energy efficiency: The energy efficiency index (EEI) of 0.18 places the ALPHA2 pump among the most energy-efficient solutions on the market, which translates into lower operating costs.
• Intelligent control: The built-in motor speed controller enables smooth speed regulation, adapting the pump's performance to the current needs of the heating system. The AUTOADAPT function automatically optimizes operating parameters, ensuring comfort and energy savings.
• Easy installation: The ALPHA plug facilitates electrical connection, and the lack of the need for an external motor protection shortens the installation time.
• Reliability: The canned rotor design minimizes the risk of the pump being blocked by contaminants, and dry-running protection protects the motor from damage.
• Hydraulic balancing: The use of the ALPHA reader and the Grundfos GO Balance application allows for quick and precise hydraulic balancing of the heating installation, which increases its efficiency and comfort.
• Wide range of applications: The pump is ideal for both single-family homes and commercial buildings, in central heating systems and domestic hot water circulation.
• Quiet operation: Thanks to the advanced construction, the pump operates quietly and discreetly, without disturbing the comfort of residents or building users.

The ALPHA2 pump is an investment in the comfort, energy savings and reliability of your heating system – a solution appreciated by both professional installers and end users.
