This unit handles primary water supply duties where consistent flow and reliable operation are required. The floating impeller configuration and integrated non-return valve help manage water column backflow when the motor stops.\u003c\/p\u003e\u003cp\u003eDriven by a 0.37 kW single-phase motor at 240V, the unit draws 3.2 Amps under normal operation. Maximum flow reaches 22.5 L\/Min, while maximum head extends to 79.4 metres at shut-off. The hydraulic design delivers stable pressure across the operating range for borehole installations.\u003c\/p\u003e\u003cp\u003eFloating impeller construction combined with the front wear ring system improves resistance to abrasive particles. The internal clearances help pass suspended solids effectively, supporting operation in groundwater containing sand or silt. The hexagonal pump shaft provides effective impeller drive throughout operation.\u003c\/p\u003e\u003cp\u003eSupplied complete with the starting control box and heatshrink kit for electrical connections. Designed for continuous submersion in liquids up to 35°C, the pump integrates stainless steel fasteners and bearings that use the pumped fluid for cooling and lubrication.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFloating hydraulic stack design allows sand and abrasives to pass easily through the pump stages\u003c\/li\u003e\n\u003cli\u003eFront wear ring works with the floating impeller to improve abrasion resistance in sandy water\u003c\/li\u003e\n\u003cli\u003eHexagonal pump shaft provides effective impeller drive throughout operation\u003c\/li\u003e\n\u003cli\u003eIntegrated stainless steel non-return valve prevents reverse flow when the pump stops\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing offers corrosion resistance for long-term submersion\u003c\/li\u003e\n\u003cli\u003eTechnopolymer impeller and diffuser materials provide corrosion resistance with lightweight technopolymer construction\u003c\/li\u003e\n\u003cli\u003eComplete with external starting control box and protective heatshrink kit for electrical connections\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50983317242103,"sku":"1GS03-1","price":1348.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-1gs03-1-4-stainless-steel-submersible-bore-pump-for-water-supply-systems-with-floating-impeller.png?v=1785325521","url":"https:\/\/foundationpumps.com.au\/products\/lowara-1gs03-1-4-stainless-steel-submersible-bore-pump-for-water-supply-systems-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
