Leo XST32-250-55 / 5.5KW 400V Centrifugal Pump And Motor
10384
Introducing the LEO XST32-250/55 Standard Centrifugal Pump, a reliable single-impeller 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 capacity up to 210 m3/h and head pressure reaching 95 m, this robust centrifugal pump delivers consistent performance in demanding industrial and commercial environments.
Constructed with an AISI304 stainless steel impeller and HT200 cast iron housing, the XST32-250/55 features axial intake and radial discharge configuration that ensures efficient fluid dynamics and minimal maintenance requirements. Its rear-entry design allows impeller and motor extraction without disconnecting the pump body from pipework, while the mechanical seal complies with DIN 24960 standards and operates via internal recirculating lubrication-making this centrifugal pump ideal for applications demanding reliability, ease of service, and continuous operation in temperatures ranging from -10 degC to 85 degC.
