Designed to support high-demand sprinkler irrigation and municipal fluid transfer, the Lowara 8GS15-1 delivers groundwater extraction from 4-inch drilled wells. This submersible bore pump provides reliable operation in agricultural and municipal networks where consistent water delivery is critical. The floating impeller design maintains hydraulic efficiency even when handling water containing suspended solids.
A 1.5 kW single-phase motor operating on 240 V draws 10.5 Amps during normal running. Maximum flow reaches 183 L/Min, while maximum head extends to 53.1 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 for systems with variable demand. This performance profile suits applications requiring both volume and moderate lift.
Floating stack construction permits sand concentrations up to 150 g/m3 to pass without damaging 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 support brackets create a rigid coupling between the pump and motor, maintaining alignment under load. The 99 mm diameter casing fits standard 4-inch boreholes, with a 50 mm threaded discharge outlet. Rated for continuous submersion in liquids up to 35°C, the complete package includes a control box and heatshrink kit for straightforward electrical terminations.
