10399
The LEO XST50-250/150 is a robust standard centrifugal pump engineered for reliable circulation and transfer of clean water and compatible liquids across diverse applications. Ideal for water supply systems, irrigation projects, air conditioning circulation, and fire fighting installations, this single-impeller pump delivers consistent performance with flow rates up to 210 m3/h and head capabilities reaching 95 meters, making it a versatile choice for both industrial and commercial water management needs.
Built with premium AISI304 stainless steel and HT200 cast iron construction, the XST50-250/150 features axial intake and radial discharge design that ensures smooth, efficient operation across a wide temperature range from -10 degC to 85 degC. Its rear-entry design allows for easy impeller and motor extraction without disconnecting the pump body from pipework, while the integrated mechanical seal compliant with DIN 24960 operates through internal recirculating liquid lubrication-all housed in a closed-construction motor with IP54 protection and overload safeguards, perfect for demanding applications requiring minimal downtime and maximum reliability.
