It provides consistent pressure distribution from deep wells to support municipal water networks and industrial distribution infrastructure. The assembly is compatible with vertical installations or horizontal mounting in systems where a minimum incline is maintained. This model serves as a dedicated tool for sectors requiring reliable head and large flow capacities.\u003c\/p\u003e\u003cp\u003ePerformance characteristics for this model include a maximum head of 107.8 m and a delivery capacity of 1333 L\/Min via the 125 mm outlet. Equipped with an 18.5 kW motor for 415v three-phase power, the unit draws a rated current of 38.5 Amps during service. The semi-axial flow design achieves a nominal flow rate for high efficiency in water transfer tasks at 2900 rpm. These metrics are verified for liquids with a density of 1.0 kg\/dm³ during industrial operation.\u003c\/p\u003e\u003cp\u003eThe structure is fabricated from cast AISI 316 Stainless Steel for the delivery head, suction support, and internal impellers. The motor is also constructed from 316 Stainless Steel and is rated for operation in liquids at temperatures up to 25°C. The system handles water with suspended sand levels of 100 g\/m³ through its four-stage configuration. A duplex stainless steel shaft and coupling transmit power to the hydraulic end to manage the generated torque.\u003c\/p\u003e\u003cp\u003eThis electric pump is rated for immersion depths up to 350 meters and features a built-in non-return valve with a stainless steel spring. Physical dimensions include a 198 mm maximum diameter including motor cable protection covers, fitting within standard borehole casings. Internal wear is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft assembly. The unit is designed for heavy-duty extraction and municipal water supply applications.\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\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\u003eInternal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.\u003c\/li\u003e\n\u003cli\u003eMechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.\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":51004072689911,"sku":"ZN855-04-3S","price":23610.62,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855043s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098064","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855043s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
