It provides consistent pressure distribution for large complexes or livestock stations from a single deep underground borehole source. The assembly is compatible with vertical deep-well installation and horizontal mounting provided a minimum inclination is maintained. This model serves as a dedicated solution for municipal networks and industrial project lifting.\u003c\/p\u003e\u003cp\u003eHydraulic performance is defined by a maximum head of 134.8 m and a delivery capacity scaling up to 1333 L\/Min through the 125 mm outlet. The unit is powered by a 22 kW motor drawing 47.3 Amps of rated current from a 415v three-phase electrical supply. Efficiency is achieved through a semi-axial flow design achieving a nominal delivery rate of 55 m³\/hr at 2900 rpm. All technical specifications are validated for liquids with standard clean water density.\u003c\/p\u003e\u003cp\u003eThe structure is fabricated from cast AISI 316 Stainless Steel for the pump body, diffusers, and impellers to handle specific water chemistry. The motor is also made of 316 Stainless Steel and is rated for contact with liquids up to 25°C during continuous service. The assembly processes water containing suspended sand levels reaching 100 g\/m³ through its five hydraulic stages. A duplex stainless steel pump shaft is used to handle mechanical torque during operation.\u003c\/p\u003e\u003cp\u003eThe unit supports immersion depths of 350 meters and features a built-in non-return valve with a stainless steel spring to prevent backflow. Physical dimensions include a 198 mm maximum diameter, fitting within standard 8-inch borehole casings. Internal clearances are maintained by technopolymer POM-C wear rings and EPDM 70 bearing bushes to ensure mechanical alignment and hydraulic performance. The unit is designed for continuous duty cycles in municipal infrastructure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\u003cli\u003eEPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.\u003c\/li\u003e\n\u003cli\u003eA duplex stainless steel taperlock system secures the 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\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\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51004072886519,"sku":"ZN855-05-3S","price":26882.19,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855053s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098075","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855053s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
