The Lowara 8GS55-3, a three-phase submersible bore pump, handles continuous operation from 4-inch boreholes where reliable high-volume, high-head delivery is essential. Its floating impeller system maintains performance in groundwater containing suspended solids.\u003c\/p\u003e\u003cp\u003eDriven by a 5.5 kW three-phase motor on 415 V, the unit draws 13.7 Amps during normal operation. Maximum flow reaches 183 L\/Min, while maximum head extends to 214.8 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 combination suits applications requiring extreme lift and moderate volume.\u003c\/p\u003e\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 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 diameter casing 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 loss\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":50985365864695,"sku":"8GS40-3","price":3294.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-8gs40-3-stainless-steel-4-submersible-bore-pump-for-residential-pressure-boosting-with-floating-impeller.png?v=1785405679","url":"https:\/\/foundationpumps.com.au\/products\/lowara-8gs40-3-stainless-steel-4-submersible-bore-pump-for-residential-pressure-boosting-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
