The Lowara 4ZN646\/3-3 delivers 1000 L\/Min from its 6-inch wet end, with a 4-inch motor connection that simplifies integration into existing systems. The microcast stainless steel housing provides structural integrity for continuous submerged operation.\u003c\/p\u003e\u003cp\u003eEvery wetted component is fabricated from AISI 316 stainless steel, offering excellent resistance to the corrosive effects of groundwater and suspended abrasives. The hydraulic stages incorporate a removable wear ring for maintenance convenience, while the integrated stainless steel non-return valve prevents reverse flow. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal clearances from premature wear.\u003c\/p\u003e\u003cp\u003eOperating on a 415V three-phase supply, the 4 kW motor draws 10.2 Amps and delivers 31 metres of shut-off head. Flow capacity reaches 1000 L\/Min through the 80 mm discharge outlet. Hydraulic performance meets EN ISO 9906 Grade 3B tolerances for reliable operation across varying duty points.\u003c\/p\u003e\u003cp\u003eImmersion depths up to 300 metres are supported by Class F insulation and IP68 protection. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. Safety hook attachment points on the discharge head facilitate secure installation and retrieval, while NEMA motor compatibility 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\u003eDischarge head features pre-drilled holes for safety hook attachment\u003c\/li\u003e\n\u003cli\u003eShaft utilizes Duplex stainless steel UNS S 31803 metallurgy\u003c\/li\u003e\n\u003cli\u003eBracing tie rods are built from AISI 316L stainless steel\u003c\/li\u003e\n\u003cli\u003eMechanical coupling component is replaceable for standard servicing\u003c\/li\u003e\n\u003cli\u003eSuction strainer uses AISI 316L stainless steel mesh\u003c\/li\u003e\n\u003cli\u003eFlange assembly conforms to standard NEMA motor connections\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":50998499803383,"sku":"4ZN646\/3-3","price":5946.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn646-3-3-stainless-steel-4kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785921728","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn646-3-3-stainless-steel-4kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
