The Lowara ZN646\/15-3N features a 6-inch wet end with 6-inch motor and NEMA coupling, delivering 1000 L\/Min at 153.2 metres of shut-off head for demanding applications. The hydraulic stages ensure stable performance across varying demand conditions.\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\u003ePowered by an 18.5 kW three-phase motor at 415V, the pump draws 38.5 Amps and achieves 153.2 metres of shut-off head. Flow capacity is 1000 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 350 metres are supported by 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 facilitate installation.\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\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":50998502064375,"sku":"ZN646\/15-3N","price":20052.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn646-15-3n-stainless-steel-18-5kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785921773","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn646-15-3n-stainless-steel-18-5kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
