Product Overview
Continuous agricultural irrigation and fluid transfer benefit from the Lowara 6GS05-12L, a streamlined 2-wire submersible bore pump for permanent submersion. This 4-inch unit is built for drilled wells and storage tanks, with a built-in capacitor eliminating the need for a surface control panel. The floating impeller design supports performance in water containing suspended solids.
A 0.55 kW single-phase motor on 240 V draws 4.3 Amps during normal operation. Maximum flow reaches 140 L/Min, while maximum head extends to 25.7 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.
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 32 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.
