This 7.5 kW radial flow pump delivers 136.1 metres of head from a 6-inch AISI 316 stainless steel wet end, engineered for continuous operation in abrasive borehole conditions. The 142 mm maximum diameter fits standard well casings.\u003c\/p\u003e\n\u003cp\u003eThe 415V three-phase motor draws 18.7 Amps and achieves 275 L\/Min maximum flow. Performance complies with EN ISO 9906 Grade 3B tolerances. The 65 mm discharge port connects to standard pipework, and the integrated non-return valve prevents reverse flow when the motor stops.\u003c\/p\u003e\n\u003cp\u003eAISI 316 stainless steel throughout the wetted end ensures corrosion resistance against aggressive groundwater. The suction strainer limits sand ingress to 100 g\/m3, and the radial flow impeller includes a removable wear ring. A replaceable coupling allows maintenance without full pump extraction.\u003c\/p\u003e\n\u003cp\u003eAt 55 kg, the unit features microcast stainless steel head and motor support castings. Safety hook holes on the delivery port secure the unit during installation. Liquid temperature tolerance is 60°C, and the pump accepts both C4S and L6W motor options.\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 shaft provides operational strength\u003c\/li\u003e\n\u003cli\u003eAISI 316L stainless steel tie rods resist external corrosion\u003c\/li\u003e\n\u003cli\u003eShaft sleeves protect internal rotating assemblies from wear\u003c\/li\u003e\n\u003cli\u003eASTM CF-8M cast stainless steel lower motor support\u003c\/li\u003e\n\u003cli\u003eEPDM elastomers maintain fluid sealing reliability\u003c\/li\u003e\n\u003cli\u003ePTFE and Graphite thrust bearings reduce operational friction\u003c\/li\u003e\n\u003cli\u003eErP 2009\/125\/EC compliant with MEI ≥ 0.40\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":50994310480119,"sku":"4ZN612\/12-3","price":6756.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-12-3-stainless-steel-7-5kw-three-phase-submersible-pump-with-radial-flow-impeller.png?v=1785755085","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-12-3-stainless-steel-7-5kw-three-phase-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
