10386
The XST40-125/11 is a compact, reliable standard centrifugal pump from LEO designed for efficient circulation and transfer of clean water and compatible liquids across a wide range of applications. Whether you need dependable performance for water supply and irrigation systems, air conditioning circulation, or fire-fighting installations, this single-impeller centrifugal pump delivers flow rates up to 210 m3/h with heads reaching 95 meters, making it an ideal choice for both commercial and industrial settings.
Built with a durable AISI304 stainless steel impeller and HT200 construction materials, the XST40-125/11 features an axial intake and radial discharge design that ensures smooth, efficient operation across temperatures from -10 degC to 85 degC. Its rear-entry design allows you to extract the impeller and motor without disconnecting the pump from your piping system, significantly reducing maintenance downtime, while the mechanical seal complies with DIN 24960 standards and is self-lubricated by the recirculating pumped liquid for extended service life and minimal intervention.
