Leo XST50-250-220 / 22KW 400V Centrifugal Pump And Motor
10401
The LEO XST50-250/220 is a reliable standard centrifugal pump engineered for the circulation and transfer of clean, non-aggressive liquids across diverse applications including water supply, irrigation systems, air conditioning circulation, and fire fighting installations. Built to deliver up to 210 m3/h at heads reaching 95 meters, this pump combines robust performance with versatile capability, making it an ideal choice for both industrial and commercial water management solutions.
Constructed as a single-impeller centrifugal pump with axial intake and radial discharge, the XST50-250/220 features a durable stainless steel AISI304 impeller paired with an HT200 cast iron body, ensuring excellent corrosion resistance and longevity. Its rear entry design allows easy impeller and motor extraction without disconnecting the pump from pipework, while the mechanical seal complies with DIN 24960 standards and is lubricated by the pumped liquid itself-a design that minimizes maintenance requirements and enhances reliability in continuous operation up to 85 degC.
