Leo 20hp Centrifugal Water pump XST denotes the standard centrifugal design compliant with EN 733. 50 is the discharge port diameter in millimeters (2 inches). 125 refers to the nominal diameter of the internal impeller in millimeters. 150 signifies the 15.0 kW motor rating, which precisely translates to 20 HP.
Unlike the high-pressure configurations of this power tier, the XST50-125/150 is hydrodynamically engineered as a low-head, high-volume
Inlet / Outlet Dimensions: Built with an asymmetric flange pattern featuring a 21⁄2" (DN65) Suction Intake and a 2" (DN50) Discharge Port.
Hydraulic Target (Duty Point): While a 20 HP pump with a larger 250mm impeller (like the XST50-250)
