Its 6-inch wet end, constructed entirely from AISI 316 stainless steel, provides exceptional corrosion resistance for demanding borehole applications. The compact 142 mm diameter fits standard casings.\u003c\/p\u003e\n\u003cp\u003eThe 415V three-phase motor draws 13.7 Amps and achieves 275 L\/Min maximum flow. Hydraulic performance conforms to EN ISO 9906 Grade 3B standards. The 65 mm discharge port connects to standard industrial pipework, while the integrated non-return valve prevents water column backflow.\u003c\/p\u003e\n\u003cp\u003eAISI 316 stainless steel across all wetted parts protects against aggressive groundwater chemistry. The suction strainer limits sand ingress to 100 g\/m3, while the radial flow impeller includes a removable wear ring for extended service life. The replaceable coupling simplifies maintenance without pump removal.\u003c\/p\u003e\n\u003cp\u003eWeighing 50 kg, the pump includes microcast stainless steel head and motor support components. Safety hook holes on the discharge head allow secure lowering. Maximum liquid temperature is 60°C, and the pump is compatible with both C4S and L6W motor series.\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 rotating elements from abrasion\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 manage axial thrust loads\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":50994310414583,"sku":"4ZN612\/11-3","price":4251.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-11-3-stainless-steel-5-5kw-three-phase-submersible-pump-with-radial-flow-impeller.png?v=1785755083","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-11-3-stainless-steel-5-5kw-three-phase-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
