The floating impeller configuration maintains stable hydraulic performance in groundwater containing suspended particulates.\u003c\/p\u003e\u003cp\u003eDriven by a 415V three-phase motor rated at 3 kW, the unit draws 7.1 Amps during normal operation. Maximum flow reaches 90 L\/Min while maximum head extends to 204 metres at shut-off. The hydraulic performance characteristics support deep well installations where significant vertical lift is required.\u003c\/p\u003e\u003cp\u003eFloating stack construction permits the pump to handle liquids containing up to 150 g\/m3 of suspended sand without mechanical binding. The front wear ring works in conjunction with the floating impeller to improve abrasion resistance, while the hexagonal shaft provides effective impeller drive. An integrated non-return valve is positioned at the outlet to block descending water columns when the motor deactivates.\u003c\/p\u003e\u003cp\u003eManufactured with a 304 Stainless Steel external casing and technopolymer diffusers and impellers. The discharge head and motor adapter are precision-cast stainless steel, offering corrosion resistance for prolonged submersion. This complete three-phase model includes a heavy-duty heatshrink kit for waterproof deep-water splices, with the pump designed for continuous operation in liquid temperatures up to 35°C.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFloating impeller system handles sand concentrations up to 150 g\/m3 without performance degradation\u003c\/li\u003e\n\u003cli\u003eHexagonal stainless steel shaft provides effective impeller drive throughout operation under load\u003c\/li\u003e\n\u003cli\u003eFront wear ring works with the floating impeller to improve abrasion resistance\u003c\/li\u003e\n\u003cli\u003eIntegrated stainless steel non-return valve prevents water column reversal and reverse rotation on shutdown\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing offers corrosion resistance for long-term submerged operation\u003c\/li\u003e\n\u003cli\u003eTechnopolymer impeller provide lightweight technopolymer construction, lowering durable hydraulic performance\u003c\/li\u003e\n\u003cli\u003eSupplied with industrial heatshrink kit for creating watertight cable splices in deep installations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50983318257911,"sku":"4GS30-3","price":2940.05,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4gs30-3-4-stainless-steel-3-phase-submersible-bore-pump-for-water-supply-systems-with-floating-impeller.png?v=1785325578","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4gs30-3-4-stainless-steel-3-phase-submersible-bore-pump-for-water-supply-systems-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
