The floating impeller design maintains performance in groundwater containing suspended solids.\u003c\/p\u003e\u003cp\u003eOperating on a 415V three-phase supply, the 0.55 kW motor draws 1.7 Amps during normal duty. Maximum flow reaches 90 L\/Min with maximum head of 47 metres at shut-off. The hydraulic performance supports fire protection system requirements effectively.\u003c\/p\u003e\u003cp\u003eFloating internal design permits the pump to handle water containing up to 150 g\/m3 of suspended sand. The front wear ring works in conjunction with the floating impeller to improve abrasion resistance, while the hexagonal shaft ensures effective impeller drive. A non-return valve locks the vertical water column on shutdown.\u003c\/p\u003e\u003cp\u003eBuilt with a 304 Stainless Steel casing and technopolymer hydraulic components. The discharge head is precision-cast stainless steel. Supplied with an industrial-grade heatshrink kit for waterproof cable splices.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES \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 impeller drive\u003c\/li\u003e\n\u003cli\u003eFront wear ring works in conjunction with the floating impeller to improve abrasion resistance\u003c\/li\u003e\n\u003cli\u003eNon-return valve prevents water column reversal on motor shutdown\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing offers corrosion resistance in submerged operation\u003c\/li\u003e\n\u003cli\u003eTechnopolymer impeller provide corrosion resistance with lightweight technopolymer construction\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":50983318094071,"sku":"4GS05-3","price":1304.75,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4gs05-3-4-stainless-steel-3-phase-submersible-bore-pump-for-fire-fighting-systems-with-floating-impeller.png?v=1785325569","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4gs05-3-4-stainless-steel-3-phase-submersible-bore-pump-for-fire-fighting-systems-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
