10394
The LEO XST40-250/110 is a reliable standard centrifugal pump designed 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. Built to deliver up to 210 m3/h with a maximum head of 95 meters, this single-impeller pump offers the dependable performance professionals expect from LEO's proven XST series.
Engineered with a durable stainless steel AISI304 impeller and HT200 construction, the XST40-250/110 features a mechanical seal compliant with DIN 24960 that is lubricated by the pump's internal recirculating liquid, eliminating external lubrication requirements. Its rear entry design allows for easy impeller and motor extraction without disconnecting the pump from your piping system, while the IP54-rated motor with external ventilation and overload protection handles ambient temperatures up to 40 degC and operates within standard liquid temperature ranges of -10 degC to 85 degC, making it ideal for both industrial and municipal water handling applications.
