This 4-inch unit provides reliable water transfer for agricultural and industrial facilities, maintaining performance even when groundwater contains suspended particulates. The floating impeller configuration ensures stable operation under varying demand.\u003c\/p\u003e\u003cp\u003eA 2.2 kW three-phase motor on 415 V draws 6.1 Amps during normal operation. 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 effective cooling, and supports up to 30 starts per hour. This performance suits applications requiring substantial lift and moderate flow.\u003c\/p\u003e\u003cp\u003eFloating stack construction permits sand concentrations 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 supports maintain rigid 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 immersion in liquids up to 35°C, the complete unit comes with a 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 hydraulic stack allows sand and abrasives to pass without binding\u003c\/li\u003e\n\u003cli\u003eHexagonal stainless steel shaft ensures effective impeller drive without slippage\u003c\/li\u003e\n\u003cli\u003eFront wear ring improves abrasion resistance in sandy groundwater conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve stops reverse flow when the pump shuts down\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing resists corrosion during long-term submersion\u003c\/li\u003e\n\u003cli\u003eTechnopolymer impeller reduces starting torque for smoother motor operation\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":50985365635319,"sku":"8GS11-3","price":1444.75,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-8gs11-3-stainless-steel-4-submersible-bore-pump-for-irrigation-systems-with-floating-impeller.png?v=1785405670","url":"https:\/\/foundationpumps.com.au\/products\/lowara-8gs11-3-stainless-steel-4-submersible-bore-pump-for-irrigation-systems-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
