Leo XST65-125-40 / 4KW 400V Centrifugal Pump And Motor
10402
The LEO XST65-125/40 is a robust standard centrifugal pump engineered for reliable circulation and transfer of clean water and non-aggressive liquids across diverse applications including water supply, irrigation systems, and air conditioning circulation. With delivery capacity up to 210 m3/h and maximum head of 95 m, this single-impeller pump delivers consistent performance for demanding industrial and commercial installations, while its operating temperature range from -10 degC to 85 degC ensures versatility across seasonal variations and climate conditions.
Built with premium AISI304 stainless steel and HT200 impeller construction, the XST65-125/40 features a durable mechanical seal compliant with DIN 24960 that is self-lubricated through internal recirculating pumped liquid, eliminating the need for external lubrication systems. Its rear-entry design enables straightforward maintenance without disconnecting pipework, while the closed-construction motor with IP54 enclosure rating and external ventilation provides reliable operation in challenging environments; the pump is ideal for fire-fighting systems, pressurised water circulation, and applications requiring PN12 maximum operating pressure in compact, space-constrained installations.
