This 4-inch unit extracts groundwater from drilled wells and cisterns, providing reliable continuous flow. The floating impeller design maintains performance in water containing suspended solids.\u003c\/p\u003e\n\u003cp\u003eHydraulic output comes from a 0.37 kW single-phase motor on 240 V, drawing 3.2 Amps during normal operation. Maximum flow reaches 22.5 L\/Min, while maximum head extends to 69.9 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.\u003c\/p\u003e\n\u003cp\u003eInside 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 non-return valve prevents destructive backflow when the motor stops.\u003c\/p\u003e\n\u003cp\u003ePrecision-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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKEY FEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-wire motor design with built-in capacitor eliminates external control box requirement\u003c\/li\u003e\n\u003cli\u003eFloating impeller system handles abrasive groundwater without performance degradation\u003c\/li\u003e\n\u003cli\u003eHexagonal stainless steel shaft provides effective drive across all pump stages\u003c\/li\u003e\n\u003cli\u003eFront wear ring improves resistance to abrasive wear in sandy conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve prevents reverse flow on motor shutdown\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel construction offers corrosion resistance during submersion\u003c\/li\u003e\n\u003cli\u003eSupplied with heatshrink kit for waterproof electrical connections\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50985367699703,"sku":"1GS03-12L","price":1713.35,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-1gs03-12l-stainless-steel-4-2-wire-submersible-bore-pump-for-domestic-water-supply-with-floating-impeller.png?v=1785405735","url":"https:\/\/foundationpumps.com.au\/products\/lowara-1gs03-12l-stainless-steel-4-2-wire-submersible-bore-pump-for-domestic-water-supply-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
