Part of the ZN895 range, this model features a 316 Stainless Steel motor configuration and provides high-volume lifting. It supports vertical installation in borehole wells or horizontal mounting in tanks provided motor immersion is maintained.\u003c\/p\u003e\u003cp\u003eConstructed from cast 316 Stainless Steel, the diffusers and suction casing handle aggregated mechanical stress during operation. The hydraulic configuration uses four stages with two reduced diameter impellers designed to handle cleaner water containing sand up to 100 g\/m³. The assembly weighs 140.6 kg and is rated for operating temperatures reaching 25°C.\u003c\/p\u003e\u003cp\u003eA 30 kW motor powers the unit on a 415v supply with a rated current of 63.8 Amps for industrial borehole duty. The pump achieves a maximum total head of 92.1 m and a maximum flow rate of 1966.7 L\/Min through a semi-axial hydraulic arrangement. These specifications support dedicated groundwater management for recreational complexes and industrial pressure maintenance systems.\u003c\/p\u003e\u003cp\u003eThermal protection features Class F insulation and an IP68 rating for submerged duty life in deep boreholes. The assembly supports installation depths up to 350 meters and features double mechanical shaft seals housed in an oil chamber for fluid containment. Internal wear rings manufactured from technopolymer POM-C and EPDM 70 bearing bushes support the duplex stainless steel shaft assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStainless steel cable covers provide mechanical protection for the power leads along the pump casing.\u003c\/li\u003e\n\u003cli\u003eA stainless steel suction strainer is fitted to exclude large solid particles from entering the hydraulic stages.\u003c\/li\u003e\n\u003cli\u003eEPDM 70 bearing bushes support the pump shaft assembly and handle the mechanical loads during rotation.\u003c\/li\u003e\n\u003cli\u003eA duplex stainless steel taperlock system secures the semi-axial impellers to the shaft for torque transfer.\u003c\/li\u003e\n\u003cli\u003eMechanical connection of the 8-inch motor follows NEMA standards to allow for compatibility with industrial systems.\u003c\/li\u003e\n\u003cli\u003eInternal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.\u003c\/li\u003e\n\u003cli\u003eThe integrated non-return valve features a stainless steel spring to prevent liquid backflow and water hammer.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51010638348535,"sku":"ZN895-04\/2B-3S","price":28185.58,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn895042b3s-stainless-steel-deep-well-8-inch-submersible-pump-semi-axial-flow-impeller.png?v=1786358409","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn895042b3s-stainless-steel-deep-well-8-inch-submersible-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
