For water supply from wells or reservoirs, domestic and industrial water transfer, and irrigation. Range photograph shown; confirm the supplied pump, motor and control equipment.
Model specifications
| Rated motor output | 7.5 kW |
|---|---|
| Supply | Three-phase 380–415 V, 50 Hz |
| Performance table reference speed | Approximately 2850 rpm |
Individual hydraulic curve and dimensional reference
Source confirmation required: The manufacturer dimension table prints overall length T(t) = 1588 mm, shorter than the separately printed pump length P = 1749 mm; P + motor length 839 mm = 2588 mm. Values are retained as printed, not silently corrected. Do not use the disputed overall length for installation; obtain a confirmed assembly drawing.
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 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.
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.
