Individual hydraulic curve and dimensional reference
Source data warning: both manufacturer hydraulic tables print 91 m head at 6 m³/h, following 85 m at 4.8 m³/h, while the manufacturer graph decreases. The figure and table reproduce the printed values, including this unresolved anomalous point. This point is not validated for duty selection. Obtain manufacturer confirmation of the required duty before ordering.
The curve joins the exact published local hydraulic table points by straight lines. No performance outside those points is assumed. Shut-off head is not the operating duty; select against required flow and total dynamic head.

Dimensions are the LEO European single-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.
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.
