Product Overview
Large-scale agricultural irrigation and municipal water transfer demand pumps that handle high volume without compromising reliability. The Lowara 8GS11-3, a three-phase submersible bore pump, manages continuous groundwater extraction from 4-inch boreholes. Its floating impeller configuration maintains performance in water containing suspended particulates.
Power comes from a 1.1 kW three-phase motor on 415 V, drawing 3.1 Amps during normal operation. Maximum flow reaches 183 L/Min, while maximum head extends to 37.2 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 performance suits systems requiring both volume and moderate lift.
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 supports maintain rigid 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 immersion in liquids up to 35°C, the complete unit comes with a heatshrink kit for secure electrical connections.
