This unit provides consistent water transfer across residential and industrial networks, maintaining performance even when groundwater contains suspended particulates. The floating impeller system ensures reliable operation under varying demand.\u003c\/p\u003e\u003cp\u003eA 2.2 kW single-phase motor on 240 V draws 14.4 Amps during normal operation. Maximum flow reaches 250 L\/Min, while maximum head extends to 56.2 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 performance suits applications requiring substantial lift and volume.\u003c\/p\u003e\u003cp\u003eInside the hydraulic section, floating impellers allow suspended particles 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 control box and 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 impeller system handles abrasive groundwater without performance degradation\u003c\/li\u003e\n\u003cli\u003eHexagonal stainless steel shaft provides effective drive across all pump stages\u003c\/li\u003e\n\u003cli\u003eFront wear ring improves resistance to abrasive wear in sandy conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve prevents reverse flow on motor shutdown\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel construction offers corrosion resistance during submersion\u003c\/li\u003e\n\u003cli\u003eTechnopolymer impeller reduces starting torque requirements\u003c\/li\u003e\n\u003cli\u003eIncludes control box and heatshrink kit for rapid installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50985366388983,"sku":"12GS22-1","price":2772.35,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-12gs22-1-stainless-steel-4-submersible-bore-pump-for-residential-pressure-boosting-with-floating-impeller.png?v=1785405697","url":"https:\/\/foundationpumps.com.au\/products\/lowara-12gs22-1-stainless-steel-4-submersible-bore-pump-for-residential-pressure-boosting-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
