Wet rotor circulation pump ALPHA2 25-60 N 130 1x230V 50Hz 6H 99411287

Next-generation circulation pump for efficient heating

The Grundfos ALPHA2 25-60 N circulation pump is an advanced solution designed for circulating water in heating systems, domestic hot water systems, and cooling installations. Its design based on maintenance-free technology ensures reliable operation and minimizes the risk of failure. It is an ideal choice for both installers looking for an efficient and easy-to-install device, and for end-users wanting to reduce the operating costs of the heating system.

Construction and functionality for demanding installations

The ALPHA2 pump is distinguished by its high energy efficiency (EEI index at 0.17), which translates into real savings. Made of high-quality materials, including stainless steel, it guarantees long-lasting and trouble-free operation even in difficult conditions. The motor speed controller, integrated with the pump, allows for smooth speed regulation, adapting the performance to the current needs of the system. This ensures that the pump operates optimally, minimizing energy consumption and noise. The pump's head is up to 6 meters with a nominal flow rate of 1.94 m³/h.

User comfort and easy installation

The ALPHA2 pump is equipped with a number of features that make it easy to use and install. The AUTOADAPT function automatically adjusts the pump's operating parameters to the specifics of the installation, ensuring optimal comfort and energy savings. The built-in night reduction mode further reduces energy consumption during off-peak heating hours. An intuitive control panel with an LED display allows easy monitoring of pump operating parameters and quick changes to settings. In addition, a special ALPHA plug facilitates electrical connection, reducing installation time. Remember the possibility of hydraulic balancing of the installation using the ALPHA Reader module and the Grundfos GO Balance application – this significantly improves the efficiency of the entire heating system.

• The pump has connection threads with a diameter of 1 1/2 inch (40) on both the inlet and outlet sides, compliant with EN 1092-2 and BSPP standards.
• The use of corrosion-resistant materials (stainless steel 304) ensures long-term reliability even when using liquids with increased air content (e.g. underfloor heating).
• Insulation class F and protection degree IPX4 guarantee safe operation in various environmental conditions (ambient temperature from 0 to 40°C).
• The maximum working pressure of the pump is 10 bar, allowing it to be used in most domestic heating installations.
• The motor power consumption is only 34W – confirming the high energy efficiency of the device.
