10391
Introducing the LEO XST40-200/55, a robust standard centrifugal pump engineered for reliable circulation and transfer of clean water and compatible liquids across diverse applications including water supply, irrigation systems, and air conditioning circulation. With delivery rates up to 210 m3/h and dynamic head capabilities reaching 95 meters, this single-impeller pump combines proven centrifugal design with dependable performance in demanding environments, making it an ideal choice for facilities and installations requiring consistent flow and pressure management.
Built with premium stainless steel AISI304 impeller construction and HT200 casing materials, the XST40-200/55 features a durable mechanical seal compliant with DIN 24960 that operates via internal recirculating liquid lubrication for extended service life. Its rear-entry design allows for convenient impeller and motor extraction without disconnecting the pump from existing pipework, while the IP54-rated motor with closed external ventilation and automatic overload protection delivers efficient operation in ambient temperatures up to 40 degC, making it perfectly suited for industrial circulation, fire-fighting systems, and commercial HVAC applications where reliability and ease of maintenance are paramount.
