Its 6-inch AISI 316 stainless steel wet end and 142 mm diameter fit standard boreholes while providing exceptional corrosion resistance for extreme extraction applications.\u003c\/p\u003e\n\u003cp\u003eThe 415V three-phase motor draws 24.2 Amps and achieves 275 L\/Min maximum flow. Performance meets EN ISO 9906 Grade 3B standards. The 65 mm discharge port connects to standard pipework, and the integrated non-return valve prevents water column backflow during motor shutdown.\u003c\/p\u003e\n\u003cp\u003eAll wetted components are AISI 316 stainless steel for corrosion resistance against aggressive groundwater. The suction strainer limits sand ingress to 100 g\/m3, while the radial flow impeller includes a removable wear ring. The replaceable coupling simplifies maintenance without pump removal.\u003c\/p\u003e\n\u003cp\u003eWeighing 85 kg, the pump features microcast stainless steel head and motor support castings. Safety hook holes on the discharge head facilitate secure lowering. Liquid temperature tolerance is 60°C, and the unit accepts L6W motor configurations.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDuplex stainless steel UNS S 31803 drive shaft provides high strength\u003c\/li\u003e\n\u003cli\u003eAISI 316L stainless steel tie rods offer corrosion-resistant bracing\u003c\/li\u003e\n\u003cli\u003eDedicated shaft sleeves protect internal rotating components\u003c\/li\u003e\n\u003cli\u003eASTM CF-8M cast stainless steel lower motor support base\u003c\/li\u003e\n\u003cli\u003eEPDM elastomers ensure dependable fluid sealing performance\u003c\/li\u003e\n\u003cli\u003ePTFE and Graphite thrust bearings reduce operational friction\u003c\/li\u003e\n\u003cli\u003eErP compliant with MEI ≥ 0.40 efficiency index\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* Motor and pump supplied separately - requires assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50994310807799,"sku":"ZN612\/21-3","price":9926.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn612-21-3-stainless-steel-11kw-three-phase-submersible-pump-with-radial-flow-impeller.png?v=1785755108","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn612-21-3-stainless-steel-11kw-three-phase-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
