Product Overview
Heavy-duty industrial water supply and large-scale agricultural irrigation require pumps that handle continuous extraction without compromising performance. The Lowara 8GS30-3, a three-phase submersible bore pump, provides exceptional fluid transfer from 4-inch boreholes. Its floating impeller system maintains efficiency in water containing suspended solids.
Driven by a 3.0 kW three-phase motor on 415 V, the unit draws 7.1 Amps during normal operation. Maximum flow reaches 183 L/Min, while maximum head extends to 113.2 metres at shut-off. The motor requires a minimum fluid velocity of 8 cm/s around the casing for adequate cooling, and supports up to 30 starts per hour. This combination suits applications requiring significant lift and moderate volume.
Inside the hydraulic section, floating impellers allow suspended particles up to 150 g/m³ to pass without compromising internal clearances. The hexagonal pump shaft delivers torque reliably across all stages, while the front wear ring works with the floating impeller to improve abrasion resistance. An integrated stainless steel check valve prevents destructive backflow when the motor stops.
Precision-cast stainless steel upper and lower support brackets maintain alignment between the pump and motor. The 99 mm diameter casing fits standard 4-inch boreholes, with a 50 mm threaded outlet. Rated for continuous submersion in liquids up to 35°C, the complete package includes a heatshrink kit for waterproof electrical connections.
