Dimensions are the LEO European three-phase reference for this model. Confirm the supplied motor, outlet, cable length, control-box configuration and assembly clearance before installation; regional assemblies may differ. Manufacturer outline is not to scale.
Dimensional source discrepancy: the published overall length is 2535 mm, while the separately printed pump and motor lengths total 2538 mm. Values are reproduced as printed, not silently recalculated. Confirm the assembly drawing and installation clearance before ordering.
Operating conditions
Published range limits: maximum liquid temperature 35°C; maximum sand content 0.25%; maximum immersion 150 m, subject to the supplied assembly and installation. Four-inch borehole family: check actual casing clearance against the pump, cable and joints. The range sheet specifies IP68 enclosure and class F insulation. Confirm appropriate motor protection and control equipment.
