This model features a Duplex Stainless Steel motor configuration and belongs to the ZN895 manufacturer series range. It is suitable for vertical installation in deep wells or horizontal deployment where a minimum 3-degree inclination ensures immersion.\u003c\/p\u003e\u003cp\u003eManufactured from cast 316 Stainless Steel, the suction support and diffusers handle aggregated structural stress during borehole duty. The hydraulic end features five stages with three reduced diameter impellers designed to handle liquids containing sand up to 100 g\/m³. The pump unit weighs 168.9 kg and is rated for liquids reaching a maximum temperature of 25°C.\u003c\/p\u003e\u003cp\u003eThe 37 kW motor operates on a 415v supply with a rated current of 81.8 Amps for borehole service cycles. The assembly achieves a maximum total head of 122.2 m and a maximum flow rate of 1966.7 L\/Min through its semi-axial hydraulic geometry. This configuration provides the pressure maintenance infrastructure needed for intensive water distribution in residential water networks and industrial facilities.\u003c\/p\u003e\u003cp\u003eSafety containment includes Class F insulation and an IP68 enclosure rating for deep borehole submerged duty. The unit supports immersion depths up to 350 meters and features double mechanical seals housed in an oil chamber for containment. Internal wear rings manufactured from POM-C and EPDM 70 bearing bushes support the duplex stainless steel shaft assembly during continuous operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\u003eMechanical connection of the 8-inch motor follows NEMA standards to allow for compatibility with industrial systems.\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\u003cli\u003eA duplex stainless steel taperlock system secures the semi-axial impellers to the shaft for torque transfer.\u003c\/li\u003e\n\u003cli\u003eInternal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.\u003c\/li\u003e\n\u003cli\u003eStainless steel cable covers provide mechanical protection for the power leads along the pump casing.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51010638676215,"sku":"ZN895-05\/3A-3R","price":42215.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn895053a3r-stainless-steel-deep-well-8-inch-submersible-pump-semi-axial-flow-impeller.png?v=1786358421","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn895053a3r-stainless-steel-deep-well-8-inch-submersible-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
