Leo XST32-200-40 / 4KW 400V Centrifugal Pump And Motor
10383
The LEO XST32-200/40 is a reliable standard centrifugal pump engineered for circulation and transfer of clean water and compatible liquids across demanding applications including water supply, irrigation systems, air conditioning circulation, and fire-fighting installations. Built on proven centrifugal pump technology, this model delivers flow rates up to 210 m3/h with heads reaching 95 m, making it an versatile choice for both industrial and commercial water handling requirements.
Constructed with a durable single-impeller design featuring an AISI304 stainless steel and HT200 cast iron composition, the XST32-200/40 incorporates a mechanical seal compliant with DIN 24960 and benefits from internal recirculating lubrication for extended operational life. Its rear-entry design allows impeller and motor extraction without disconnecting the pump body from pipework, minimizing downtime during maintenance, while the robust IP54-rated motor with external ventilation and overload protection ensures reliable performance in ambient temperatures up to 40 degC and operating conditions from -10 degC to 85 degC.
