10393
Introducing the LEO XST40-250/92 Standard Centrifugal Pump, a robust single-impeller pump engineered for reliable circulation and transfer of clean water and compatible liquids across diverse applications. This versatile workhorse excels in water supply and irrigation systems, air conditioning circulation, and fire-fighting installations, delivering flow rates up to 210 m3/h with operating heads reaching 95 meters. Built on decades of centrifugal pump expertise, the XST series combines proven performance with straightforward, field-proven design principles.
Constructed with premium AISI304 stainless steel and ductile iron components, this pump features a durable single-impeller design with axial intake and radial discharge configuration that ensures smooth, efficient operation across demanding environments. Its heavy-duty construction incorporates a mechanical seal compliant with DIN 24960, while the innovative rear-entry design allows impeller and motor extraction without disconnecting the pump body from pipework-reducing installation and maintenance downtime significantly. Engineered to handle liquid temperatures from -10 degC to 85 degC at pressures up to 12 bar, with an IP54-rated motor featuring overload protection and external ventilation, the XST40-250/92 is ideally suited for both municipal water systems and industrial applications requiring dependable, long-service-life performance.
