Leo AC550CH2 / 5.5KW 400V Centrifugal Pump And Motor
15552
Introducing the LEO AC550CH2, a robust centrifugal pump engineered for reliable water transfer across residential and industrial applications. This single-phase centrifugal pump excels in urban water supply systems, pressure boosting for high-rise buildings, fire-fighting operations, garden irrigation, and long-distance water transfer projects where consistent performance is essential. Its versatility extends to heating, ventilation, and air conditioning systems, as well as hot and cold water circulation applications.
Built with a cast iron pump body featuring special anti-rust treatment for exceptional durability, the AC550CH2 incorporates an AISI 304 stainless steel shaft that resists corrosion in demanding environments. Paired with a copper-wound IE2 motor delivering low-noise operation and extended bearing life, this pump handles clean water and similar liquids up to 60 degC with maximum suction capability of 8 meters. The IPX4-rated enclosure and F-class insulation ensure reliable performance even in challenging conditions, making it an ideal choice for both continuous industrial circulation and intermittent domestic pressure-boosting requirements.
