Product Overview
Industrial water supply and municipal distribution systems require pumps that operate continuously without interruption. The Lowara 8GS07-3, a three-phase submersible bore pump, provides consistent groundwater extraction from 4-inch boreholes for commercial and agricultural networks. Its floating impeller design maintains performance in water containing suspended solids.
A 0.75 kW three-phase motor on 415 V draws 2.4 Amps during normal running. Maximum flow reaches 183 L/Min, while maximum head extends to 26.6 metres at shut-off. The motor requires a minimum fluid velocity of 8 cm/s around the casing for effective cooling, and supports up to 30 starts per hour. This efficiency makes the unit suitable for continuous operation in industrial settings.
Floating impeller construction permits the passage of suspended sand up to 150 g/m³ without compromising internal clearances or efficiency. The hexagonal pump shaft ensures reliable torque transfer 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 casing diameter 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.
