The Lowara 4ZN646\/5-3 handles these duties with its 6-inch wet end and 4-inch motor configuration, delivering 1000 L\/Min for large-scale water management projects. The impeller and diffuser arrangement ensures efficient energy transfer across the operating range.\u003c\/p\u003e\u003cp\u003eThe pump incorporates AISI 316 stainless steel throughout the wet end, protecting every component from corrosion and abrasive wear. The radial flow impeller includes a removable wear ring for simplified maintenance, while the integrated non-return valve prevents water column reversal during shutdown. The suction strainer limits suspended sand to 100 grams per cubic metre, preserving internal component integrity.\u003c\/p\u003e\u003cp\u003eDriven by a 7.5 kW three-phase motor at 415V, the pump draws 18.1 Amps and achieves 51.7 metres of shut-off head. Maximum flow is 1000 L\/Min through the 80 mm discharge port. Performance complies with EN ISO 9906 Grade 3B tolerances for consistent hydraulic output.\u003c\/p\u003e\u003cp\u003eClass F insulation with IP68 rating supports immersion depths to 300 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. Safety hook holes on the discharge head enable secure handling during installation and retrieval, while NEMA motor coupling simplifies assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e4Z = 6\" wet end with 4\" Lowara motor\u003c\/strong\u003e\u003c\/p\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eDelivery port incorporates integrated safety hook attachment points\u003c\/li\u003e\n\u003cli\u003eDrive shaft is manufactured from Duplex stainless steel UNS S 31803\u003c\/li\u003e\n\u003cli\u003eExternal tie rods are constructed from AISI 316L stainless steel\u003c\/li\u003e\n\u003cli\u003eSupplied with a replaceable coupling component for standard maintenance\u003c\/li\u003e\n\u003cli\u003eIntake strainer is fabricated from AISI 316L stainless steel\u003c\/li\u003e\n\u003cli\u003eLower motor support matches standard NEMA mounting dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e* Motor and pump supplied separately - requires assembly\u003c\/p\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50998499999991,"sku":"4ZN646\/5-3","price":6723.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn646-5-3-stainless-steel-7-5kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785921730","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn646-5-3-stainless-steel-7-5kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
