Leo XST40-125-15 / 1.5KW 400V Centrifugal Pump And Motor
10387
The LEO XST40-125/15 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 systems, irrigation networks, air conditioning circulation, and fire fighting installations. With its impressive delivery capacity of up to 210 m3/h and head capabilities reaching 95 meters, this single-impeller centrifugal pump delivers the performance needed for demanding industrial and commercial water handling tasks.
Built with premium AISI304 and HT200 impeller construction, the XST40-125/15 features a durable mechanical seal compliant with DIN 24960 and benefits from intelligent self-lubrication through internal recirculating pumped liquid, eliminating external lubrication requirements. Its rear-entry design allows convenient extraction of the impeller and motor assembly without disconnecting the pump body from pipework, while the closed-construction motor with IP54 enclosure rating and F-class insulation ensures reliable operation in ambient temperatures up to 40 degC, making this centrifugal pump ideal for continuous duty applications where accessibility and low maintenance are priorities.
