The Lowara 8GS15-3, a three-phase submersible bore pump, provides reliable service from 4-inch boreholes. Its floating impeller design maintains performance in water containing suspended solids.\u003c\/p\u003e\u003cp\u003eDriven by a 1.5 kW three-phase motor on 415 V, the unit draws 4.4 Amps during normal operation. 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. This combination suits applications requiring substantial volume and lift.\u003c\/p\u003e\u003cp\u003eFloating stack construction permits the passage of sand concentrations up to 150 g\/m3 without compromising internal clearances. The hexagonal pump shaft ensures reliable torque transfer 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.\u003c\/p\u003e\u003cp\u003ePrecision-cast stainless steel upper and lower support brackets maintain alignment between the pump and motor. The 99 mm casing diameter fits standard 4-inch boreholes, with a 50 mm threaded outlet. Rated for continuous submersion in liquids up to 35°C, the complete package includes a heatshrink kit for waterproof electrical connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKEY FEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\u003eTechnopolymer impeller reduces starting torque requirements\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":50985365602551,"sku":"8GS07-3","price":1452.05,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-8gs07-3-stainless-steel-4-submersible-bore-pump-for-residential-water-supply-with-floating-impeller.png?v=1785405668","url":"https:\/\/foundationpumps.com.au\/products\/lowara-8gs07-3-stainless-steel-4-submersible-bore-pump-for-residential-water-supply-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
