Dimensions are the published LEO European single-phase reference for this model. Confirm the supplied motor, outlet, cable length and control-box configuration before installation; regional assemblies may differ. Manufacturer outline is not to scale.
Operating conditions
Maximum liquid temperature 35°C; maximum sand content 0.25%; maximum immersion 150 m subject to the selected assembly and installation. Three-inch borehole family: check actual casing clearance against the pump, cable and joint dimensions. IP68 enclosure and class F insulation are specified in the range sheet. Confirm correct motor protection and control equipment for the supplied unit.
Source discrepancy: the local LEO sheet prints 124 m at zero flow; the European sheet prints 125 m. This page and curve use the local sheet’s 124 m value. Confirm the supplied variant before final duty selection.
