This 7.5 kW radial flow pump features all-AISI 316 stainless steel construction and a 6-inch wet end, designed for demanding lift applications where reliability is critical. The 142 mm diameter fits standard boreholes.\u003c\/p\u003e\n\u003cp\u003eThe three-phase 415V motor draws 18.7 Amps and delivers 275 L\/Min maximum flow. Performance meets EN ISO 9906 Grade 3B tolerances. The 65 mm discharge port accommodates standard piping, while the integrated non-return valve prevents water column backflow.\u003c\/p\u003e\n\u003cp\u003eCorrosion resistance from AISI 316 stainless steel protects against aggressive groundwater chemistry, while the suction strainer limits sand ingress to 100 g\/m3. The radial flow impeller includes a removable wear ring for extended service intervals. The replaceable coupling allows component access without full pump removal.\u003c\/p\u003e\n\u003cp\u003eWeighing 58 kg, the pump features microcast stainless steel head and motor support components. Safety hook holes on the discharge head secure the unit during installation. Maximum liquid temperature is 60°C, and the pump is compatible with both C4S and 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 ensures torsional strength\u003c\/li\u003e\n\u003cli\u003eAISI 316L stainless steel tie rods provide corrosion-resistant bracing\u003c\/li\u003e\n\u003cli\u003eShaft sleeves protect rotating assemblies from abrasive wear\u003c\/li\u003e\n\u003cli\u003eASTM CF-8M cast stainless steel lower motor support base\u003c\/li\u003e\n\u003cli\u003eEPDM elastomers deliver reliable fluid sealing integrity\u003c\/li\u003e\n\u003cli\u003ePTFE and Graphite thrust bearings manage axial loads effectively\u003c\/li\u003e\n\u003cli\u003eMEI ≥ 0.40 compliant with ErP regulations\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":50994310512887,"sku":"4ZN612\/15-3","price":7431.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn612-15-3-stainless-steel-7-5kw-three-phase-submersible-pump-with-radial-flow-impeller.png?v=1785755087","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn612-15-3-stainless-steel-7-5kw-three-phase-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
