This model handles clean fluids containing suspended sand concentrations up to 100 g\/m³ during continuous operation. It is suitable for submerged installation in 6-inch boreholes to provide a steady supply of clean water for agricultural and civil distribution networks.\u003c\/p\u003e\u003cp\u003eConstructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for immersion in aggressive groundwater environments. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm. The unit weighs 37 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency in industrial applications.\u003c\/p\u003e\u003cp\u003eThe 4 kW motor operates on a 415v supply with a rated current of 10.2 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 head for integration into piping systems.\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 300 meters with compatible 4-inch motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep wells.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e4Z = 6\" wet end with 4\" Lowara 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 142 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":50996220854519,"sku":"4ZN622\/4-3","price":4333.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn62243-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller.png?v=1785836828","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn62243-stainless-steel-6-inch-deep-well-submersible-bore-pump-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
