Wet rotor circulation pump ALPHA2 25-60 N 180 1x230V 50Hz 6H 99411424

Circulation pump – an effective solution for your installation

The Grundfos ALPHA2 25-60 N circulation pump is an advanced device designed for circulating water in heating, air conditioning and domestic hot water systems. It is characterized by high energy efficiency, which translates into lower operating costs. The construction with a stainless steel housing ensures durability and corrosion resistance, and the built-in controller allows for precise adjustment of the pump's operation to current needs. It is an ideal choice for both new and modernized installations.

Construction and application

The ALPHA2 N pump has been designed with ease of installation and use in mind. Its compact dimensions (connection length 180 mm) allow for installation in a limited space. It has 1 ½ inch (BSPP) threaded connections, which facilitates integration with the existing system. The device is adapted to work with media at temperatures from +2°C to +110°C and a maximum working pressure of 10 bar. This makes it suitable for a variety of applications, from underfloor heating to domestic hot water recirculation.

Key features and benefits

• High energy efficiency: Energy class A and energy efficiency index (EEI) of 0.17 guarantee minimal electricity consumption, which translates into financial savings.
• AUTOADAPT function: Automatically adjusts the pump's operating parameters to the characteristics of the installation, ensuring optimal comfort and minimal energy consumption.
• Dry-running protection: Protects the pump from damage in the event of a lack of medium flow, increasing its lifespan.
• Built-in controller: Allows precise setting of the pump's operating parameters, such as rotational speed or characteristic curve.
• Durable construction: The housing made of stainless steel (grade 304 – 1.4308) provides corrosion resistance and long-term reliability.
• Low noise level: The pump operation is quiet and discreet, increasing user comfort.
• Easy installation: The innovative plug simplifies electrical connection, and the intuitive LED display facilitates configuration and monitoring of the device.
• Nominal flow rate: 1.94 m³/h at a head of 32.16 kPa provides adequate performance in typical domestic installations.
• Maximum performance: Up to 3.4 m³/h and a maximum head of 6 meters allow the pump to be used in more demanding heating systems.

The ALPHA2 N pump is an investment in the comfort, savings and reliability of your heating or air conditioning installation. Its advanced functions and solid construction guarantee long-term and trouble-free operation.
