Wet rotor circulation pump type ALPHA1 25-80 N 180 1x230 50Hz 6H ALPHA1 series 99199594

Circulation pump for heating and domestic hot water systems

The ALPHA1 25-80 N 180 circulation pump is a high-efficiency, maintenance-free pump designed to operate in various heating installations – both with constant and variable flow rates. It is suitable for central heating systems, domestic hot water systems, and installations with solar collectors. Its construction based on a permanent magnet motor guarantees energy-saving and quiet operation.

Construction and application

The ALPHA1 pump is characterized by its compact design and ease of installation. Made of high-quality materials, including stainless steel (housing), it ensures durability and corrosion resistance. It is intended for circulating water or a mixture of water and glycol. The installation length of 180 mm makes it easier to replace older pump models. Threaded connections 1 1/2 inch (40) compliant with EN 1092-2 standard ensure compatibility with most existing installations. The maximum head of the pump is 8 meters, and the maximum flow rate is 1.94 m³/h.
