The unit is configured for submerged operation inside 6-inch boreholes to support large-scale irrigation systems and water feature supply. Its technical design provides consistent pressurized transfer from underground sources to surface distribution networks in civil and industrial sectors.\u003c\/p\u003e\u003cp\u003eConstructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for aggressive groundwater. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm. The unit weighs 54 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to maintain stable hydraulic performance in industrial duties.\u003c\/p\u003e\u003cp\u003eThe 4 kW motor operates on a 415v supply with a rated current of 9.17 Amps. The pump achieves a maximum head of 54.2 m and a maximum flow of 500 L\/Min through a 65 mm discharge outlet. Multistage radial hydraulics provide efficient water delivery throughout the operating range. Connection is made through Rp 2 1\/2-inch threads on the microcast discharge head.\u003c\/p\u003e\u003cp\u003eThe pump features a duplex stainless steel shaft protected by shaft sleeves and tungsten carbide bushings. An integrated stainless steel non-return valve prevents backflow, while removable wear rings simplify servicing. The assembly supports installation depths reaching 350 meters with compatible 6-inch L6W motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure placement in deep borehole sites.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eZ = 6\" wet end with 6\" Lowara L6C motor\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMicrocast stainless steel discharge head and motor support components.\u003c\/li\u003e\n\u003cli\u003eIntegrated high-grade stainless steel non-return valve for backflow prevention.\u003c\/li\u003e\n\u003cli\u003eRadial centrifugal impellers manufactured from AISI 316L stainless steel.\u003c\/li\u003e\n\u003cli\u003eRemovable stainless steel wear rings for internal hydraulic renewal.\u003c\/li\u003e\n\u003cli\u003ePump shaft manufactured from duplex stainless steel for mechanical stability.\u003c\/li\u003e\n\u003cli\u003eInternal protection provided by stainless steel shaft sleeves and bushings.\u003c\/li\u003e\n\u003cli\u003eSuitable for continuous vertical installation in 6-inch boreholes.\u003c\/li\u003e\n\u003cli\u003eMaximum external diameter of 144 mm including the integrated cable guard.\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":50996220952823,"sku":"ZN622\/4-3","price":6367.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn62243-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller.png?v=1785836833","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn62243-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
