Leo XST65-200-185 / 18.5KW 400V Centrifugal Pump And Motor
12217
The LEO XST65-200/185 is a reliable standard centrifugal pump engineered for circulation and transfer of clean, non-aggressive liquids across demanding applications including water supply, irrigation systems, air conditioning circulation, and fire fighting installations. With delivery rates up to 210 m3/h and head capabilities reaching 95 meters, this single-impeller centrifugal pump delivers consistent performance in temperature ranges from -10 degC to 85 degC, making it an ideal choice for facilities requiring robust liquid handling solutions.
Built with premium stainless steel AISI304 impeller construction and cast iron HT200 housing, the XST65-200/220 features a mechanical seal compliant with DIN 24960 that is lubricated by the pump's internally recirculated liquid, eliminating the need for external lubrication systems. Its intelligent rear-entry design allows impeller and motor extraction without disconnecting the pump from pipework, significantly reducing installation and maintenance downtime, while the IP54-rated closed motor with external ventilation and IE2 efficiency rating ensures long-term operational reliability and energy efficiency in industrial and commercial water circulation applications.
