The Lowara ZN646\/20-3N delivers 205.4 metres of shut-off head from its 6-inch wet end, with a 26 kW motor and NEMA coupling configuration that provides ample power for demanding applications. The hydraulic stages ensure efficient energy transfer across the operating range.\u003c\/p\u003e\u003cp\u003eEvery wetted component is fabricated from AISI 316 stainless steel, providing long-term corrosion resistance in aggressive groundwater environments. The impeller and diffuser arrangement includes a removable wear ring for maintenance convenience, 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.\u003c\/p\u003e\u003cp\u003eDriven by a 26 kW three-phase motor at 415V, the pump draws 56.5 Amps and achieves 205.4 metres of shut-off head. Flow capacity reaches 1000 L\/Min through the 80 mm discharge port. Hydraulic performance complies with EN ISO 9906 Grade 3B tolerances for consistent output.\u003c\/p\u003e\u003cp\u003eClass F insulation with IP68 rating supports immersion depths to 350 metres. The Duplex stainless steel shaft provides mechanical strength, while AISI 316L tie rods offer structural integrity. Safety hook holes facilitate installation, and NEMA motor compatibility simplifies assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eZ = 6\" wet end with 6\" Lowara L6C 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":50998502424823,"sku":"ZN646\/20-3N","price":26087.44,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn646-20-3n-stainless-steel-26kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785921779","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn646-20-3n-stainless-steel-26kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
