It features two reduced impellers for head fine-tuning to provide a solution for high-volume distribution in farming infrastructure. The pump is compatible with vertical installation or horizontal deployment in tanks where a 3-degree incline is maintained. This configuration serves agricultural and industrial sectors needing precise pressure parameters and consistent lifting.\u003c\/p\u003e\u003cp\u003ePerformance metrics are defined by a maximum head of 96.3 m and a maximum delivery rate of 1216 L\/Min through the 125 mm outlet. Powered by a 15 kW motor on a 415v three-phase supply, the unit draws 32.1 Amps of rated current during operation. The semi-axial flow design achieves high efficiency in water transfer tasks at a rotation speed of 2900 rpm. These parameters are validated for liquids with a density of 1.0 kg\/dm³ and standard clean water viscosity.\u003c\/p\u003e\u003cp\u003eWet end components are fabricated from cast AISI 316 Stainless Steel for wetted parts including the diffusers, impellers, and delivery casing. The motor is also made of 316 Stainless Steel and is rated for contact with liquids up to 25°C during continuous service. The system processes water with suspended sand levels of 100 g\/m³ without loss of material integrity. A duplex stainless steel shaft and coupling are used to transmit power to the four hydraulic stages.\u003c\/p\u003e\u003cp\u003eThe unit handles immersion depths of 350 meters and features a 198 mm maximum overall diameter including cable protection covers. A built-in non-return valve with a stainless steel spring is situated in the delivery head to prevent backflow and reverse rotation. Internal clearance is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft assembly. This electric pump is intended for continuous industrial and municipal duty in deep borehole systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.\u003c\/li\u003e\n\u003cli\u003eThe integrated non-return valve features a stainless steel spring to prevent fluid backflow.\u003c\/li\u003e\n\u003cli\u003eMechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.\u003c\/li\u003e\n\u003cli\u003eInternal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.\u003c\/li\u003e\n\u003cli\u003eA stainless steel suction strainer excludes large particles from entering the hydraulic stages.\u003c\/li\u003e\n\u003cli\u003eEPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.\u003c\/li\u003e\n\u003cli\u003eStainless steel cable covers provide mechanical protection for motor power leads along the casing.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51004072591607,"sku":"ZN855-04\/2A-3S","price":22976.69,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855042a3s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098060","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855042a3s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
