Product Overview
Borehole systems requiring high-head performance benefit from the Lowara 8GS22-1, a 4-inch submersible bore pump engineered for pressure boosting and large-scale agricultural distribution. This unit delivers consistent water transfer across residential and industrial networks, maintaining performance even when groundwater contains suspended particulates. The floating impeller configuration ensures reliable operation under varying drawdown conditions.
Power comes from a 2.2 kW single-phase motor running on 240 V, drawing 14.4 Amps during normal duty. Maximum flow reaches 183 L/Min, while maximum head extends to 81.2 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 substantial lift and moderate flow.
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. A stainless steel non-return valve integrated into the discharge head prevents reverse flow when the pump stops, protecting against water hammer.
Precision-cast stainless steel upper and lower supports maintain rigid alignment between the pump and motor under load. The 99 mm diameter casing fits standard 4-inch boreholes, with a 50 mm threaded outlet. Rated for continuous immersion in liquids up to 35°C, the complete unit comes with a control box and heatshrink kit for secure electrical connections.
