Materials

Standard (economy) — SUS304 sleeve + engineering-plastic impeller & diffuser + SUS304 shaft (Best price for clean-water irrigation / domestic supply)
Corrosion (option) — SUS316 sleeve + plastic impeller (plastic is inherently corrosion-proof)
Sandy (option) — SUS304 impeller upgrade (plastic wears faster in sand)

Premium components

100% copper motor windings
Class F (155 °C) insulation system
NSK-grade sealed ball bearings
SUS304 shaft + engineering-plastic impellers
Silicon-carbide (SiC) mechanical seal
Oil-cooled motor
PMSM + sensorless FOC sine-wave controller, MPPT >99%

Recommended cable

PV-to-controller & motor cable 2.5–4 mm² by model (copper, sized for a ~50 m run; step up one size per additional ~50 m of drop).

Per-model cable cross-section is listed in the specification table above (mm² column).
