10404
The LEO XST65-125/75 is a reliable standard centrifugal pump engineered for circulation and transfer of clean water and non-aggressive liquids across diverse applications including water supply, irrigation systems, air conditioning circulation, and fire fighting installations. Built on proven centrifugal pump technology, this single-impeller model delivers consistent performance with flow rates up to 210 m3/h and head capabilities reaching 95 meters, making it an ideal choice for demanding industrial and commercial water handling requirements.
Constructed with premium AISI304 stainless steel and HT200 cast iron components, the XST65-125/75 features axial intake and radial discharge design with rear entry access, allowing impeller and motor extraction without disconnecting the pump body from pipework. Its robust mechanical seal complies with DIN 24960 standards and operates reliably across temperatures from -10 degC to 85 degC under maximum pressure of 12 bar, while the closed-construction motor with IP54 enclosure class and external ventilation provides dependable operation in challenging environments up to +40 degC ambient conditions.
