The Lowara 4ZN660\/3-3 handles 1300 L\/Min through its 6-inch wet end with 4-inch motor connection, making it suitable for farm irrigation networks and water feature applications. The multi-stage hydraulic assembly provides stable output across varying duty cycles.\u003c\/p\u003e\u003cp\u003eAISI 316 stainless steel construction throughout the wet end offers excellent resistance to corrosion and abrasive wear. The impeller incorporates a removable wear ring for simplified maintenance, while the integrated non-return valve prevents water column reversal. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal clearances. The microcast stainless steel housing provides structural integrity for long-term submersion.\u003c\/p\u003e\u003cp\u003eOperating on a 415V three-phase supply, the 5.5 kW motor draws 13.2 Amps and achieves 31.9 metres of shut-off head. Flow capacity is 1300 L\/Min through the 80 mm discharge outlet. Performance testing to EN ISO 9906 Grade 3B ensures reliable operation across the full duty range.\u003c\/p\u003e\u003cp\u003eSubmersion depths up to 300 metres are supported with Class F insulation and IP68 protection. The Duplex stainless steel shaft provides mechanical strength for continuous operation, while AISI 316L tie rods offer additional structural support. NEMA motor compatibility simplifies assembly, and safety hook holes on the discharge head facilitate installation.\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\u003cli\u003eMaximum permissible suspended sand concentration of 100 g\/m3\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":51001341346039,"sku":"4ZN660\/3-3","price":5345.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn660-3-3-stainless-steel-5-5kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1786007636","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn660-3-3-stainless-steel-5-5kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
