The Lowara ZN646\/3-3 features a 6-inch wet end paired with a 6-inch motor, delivering 1000 L\/Min for demanding water transfer applications. The hydraulic stages maintain stable performance across varying duty cycles.\u003c\/p\u003e\u003cp\u003eCorrosion resistance is achieved through all-stainless steel construction using AISI 316 material throughout the wet end, providing superior protection in aggressive groundwater environments. The impeller and diffuser arrangement is equipped with a removable wear ring, simplifying maintenance and reducing downtime. The integrated non-return valve prevents reverse flow, while the suction strainer limits sand ingress to 100 grams per cubic metre.\u003c\/p\u003e\u003cp\u003eOperating on a 415V three-phase supply, the 4 kW motor draws 9.89 Amps and delivers 31 metres of shut-off head. Maximum 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 on the discharge head 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":50998500032759,"sku":"ZN646\/3-3","price":6962.85,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn646-3-3-stainless-steel-4kw-deep-well-submersible-pump-with-radial-flow-impeller.png?v=1785921732","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn646-3-3-stainless-steel-4kw-deep-well-submersible-pump-with-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
