Specified for vertical installation in 6-inch boreholes, the unit manages clean water transfer duties where sand particles do not exceed 100 g\/m³ in reservoirs or deep sources. The assembly provides a consistent source of pressurized clean water for high-volume agricultural and civil distribution networks.\u003c\/p\u003e\u003cp\u003eConstructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for immersion in corrosive groundwater. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm. The unit weighs 64 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys for technical consistency in high-temperature industrial duties.\u003c\/p\u003e\u003cp\u003eThe 7.5 kW motor operates on a 415v supply with a rated current of 17.6 Amps. The pump achieves a maximum head of 95.1 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 to the system is via 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 L6C motors. Discharge ports include holes for safety hook attachment to facilitate secure placement in borehole environments.\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":50996221640951,"sku":"ZN622\/7-3N","price":10714.17,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn62273n-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller.png?v=1785836862","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn62273n-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
