10389
The LEO XST40-160/30 is a reliable standard centrifugal pump engineered for circulation and transfer of clean, chemically non-aggressive water and other liquids across diverse applications including water supply, irrigation systems, air conditioning circulation, and fire fighting installations. With delivery capacity up to 210 m3/h and maximum head of 95 m, this single-impeller pump delivers consistent performance in demanding environments where dependable fluid handling is essential.
Built with a durable stainless steel AISI304 impeller and HT200 pump body, the XST40-160/30 features axial intake and radial discharge design that enables convenient rear entry maintenance-allowing impeller and motor extraction without disconnecting the pump from pipework. Its mechanical seal complies with DIN 24960 standards and operates across temperatures from -10 degC to 85 degC, while the IE3-compatible motor delivers energy efficiency with IP54 protection and overload safeguards, making it an ideal choice for continuous operation in commercial and industrial water circulation applications.
