Leo XST65-125-55 / 5.5KW 400V Centrifugal Pump And Motor
10403
The LEO XST65-125/55 is a reliable standard centrifugal pump engineered for circulation and transfer applications across water supply, irrigation, air conditioning systems, and fire fighting installations. Built to handle clean, chemically non-aggressive liquids with delivery rates up to 210 m3/h and operating heads reaching 95 m, this pump delivers consistent performance in demanding commercial and industrial environments.
Featuring a single-impeller design with axial intake and radial discharge, the XST65-125/55 is constructed with a corrosion-resistant AISI304 impeller paired with an HT200 cast iron body for durability and longevity. Its mechanical seal complies with DIN 24960 and benefits from internal recirculating lubrication, while the rear entry design allows impeller and motor extraction without disconnecting the pump from pipework-making maintenance straightforward and minimizing downtime on your installation.
