This unit delivers consistent water transfer across residential and industrial networks, maintaining performance even when groundwater contains suspended particulates. The floating impeller configuration ensures reliable operation under varying drawdown conditions.\u003c\/p\u003e\u003cp\u003ePower comes from a 2.2 kW single-phase motor running on 240 V, drawing 14.4 Amps during normal duty. Maximum flow reaches 183 L\/Min, while maximum head extends to 81.2 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 substantial lift and moderate flow.\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. A stainless steel non-return valve integrated into the discharge head prevents reverse flow when the pump stops, protecting against water hammer.\u003c\/p\u003e\u003cp\u003ePrecision-cast stainless steel upper and lower supports maintain rigid alignment between the pump and motor under load. The 99 mm diameter casing fits standard 4-inch boreholes, with a 50 mm threaded outlet. Rated for continuous immersion in liquids up to 35°C, the complete unit comes with a control box and heatshrink kit for secure electrical connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKEY FEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFloating impeller design 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\u003eIncludes control box and heatshrink kit for rapid installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50985365504247,"sku":"8GS11-1","price":1682.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-8gs11-1-stainless-steel-4-submersible-bore-pump-for-domestic-water-supply-with-floating-impeller.png?v=1785405660","url":"https:\/\/foundationpumps.com.au\/products\/lowara-8gs11-1-stainless-steel-4-submersible-bore-pump-for-domestic-water-supply-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
