This unit provides large-scale water transfer with exceptional reliability for continuous extraction. Its floating impeller configuration supports performance in water containing suspended solids.\u003c\/p\u003e\u003cp\u003eA 2.2 kW single-phase motor on 240 V draws 14.4 Amps during normal operation. Maximum flow reaches 367 L\/Min, while maximum head extends to 45.9 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 massive volume and moderate lift.\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 ensures reliable torque transfer 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 support brackets maintain alignment between the pump and motor. The 99 mm casing diameter fits standard 4-inch boreholes, with a 50 mm threaded outlet. Rated for continuous submersion in liquids up to 35°C, the complete package includes a control box and heatshrink kit for straightforward electrical terminations.\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\u003eIncludes control box and heatshrink kit for immediate installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50985367470327,"sku":"16GS22-1","price":3172.85,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-16gs22-1-stainless-steel-4-submersible-bore-pump-for-residential-water-supply-with-floating-impeller.png?v=1785405719","url":"https:\/\/foundationpumps.com.au\/products\/lowara-16gs22-1-stainless-steel-4-submersible-bore-pump-for-residential-water-supply-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
