Specified for submerged service in 6-inch boreholes, the assembly manages clean water transfer where sand concentrations do not exceed 100 g\/m³ during standard operation. The unit is suitable for vertical installation in reservoirs or deep underground sources to maintain distribution network pressure.\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 107 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys for use in high-temperature fluid handling duties.\u003c\/p\u003e\u003cp\u003eThe 18.5 kW motor operates on a 415v supply with a rated current of 39.3 Amps. The pump achieves a maximum head of 241.9 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 network is made 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 L6W motors. Discharge ports include holes for safety hook attachment to ensure 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":50996221280503,"sku":"ZN622\/18-3","price":11859.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn622183-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller.png?v=1785836848","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn622183-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
