Wet rotor circulation pump type ALPHA1 25-60 N 180 1x230 50Hz 6H ALPHA1 series 99199593

Circulation pump for heating and domestic hot water systems

The ALPHA1 25-60 N 180 circulation pump is a high-efficiency, maintenance-free pump designed for efficient circulation of liquids in heating systems, both in residential and commercial buildings. Made of durable stainless steel, it also performs well in domestic hot water systems. Its design and applied technologies ensure reliable operation and minimize energy consumption.

Design and application

The ALPHA1 N pump features integrated differential pressure control and the ability to choose from three operating characteristics: proportional, constant pressure, and constant curve. This allows for optimal adaptation of the pump to specific installation conditions and user needs. Equipped with a clear LED display, it provides information on the operating status, current power consumption, and any warnings. Automatic venting facilitates pump start-up and ensures trouble-free operation. The compact design with the pump head and control panel simplifies installation in most typical installations.

Advantages and benefits

• High energy efficiency: An energy efficiency index (EEI) of 0.2 guarantees low operating costs and compliance with ErP standards.
• Durable construction: The stainless steel body (grade 304 – 1.4308) ensures long life and corrosion resistance.
• Versatility: The ability to operate in different modes (proportional, constant pressure, constant curve) allows adaptation to different types of installations.
• Low noise level: Quiet operation of the pump (below 43 dB) ensures comfortable use.
• Maintenance-free: The absence of a mechanical seal and lubrication of the bearings with the pumped liquid eliminates the need for regular maintenance.
• Easy installation: The compact design simplifies installation even in tight spaces.
• Wide temperature range: Operation in a temperature range from 0 to 110°C allows for use in various heating and domestic hot water systems.
• Protections: Insulation class F and motor thermal protection ensure safe operation of the device.

The ALPHA1 25-60 N 180 pump is a solid solution for both professional installers and end-users looking for a reliable and energy-efficient circulation pump. Its versatility and ease of use make it an ideal choice for modern heating and domestic hot water systems. The maximum head is 6 meters with a nominal flow rate of 1.94 m³/h.
