It serves as a solution for deep borehole extraction in industrial water supply projects and municipal distribution networks requiring precise lift. The pump is compatible with vertical installations and horizontal deployment in distribution systems with a minimum inclination. This model is intended for sectors needing large flow capacities from underground aquifers via reduced impeller matching.\u003c\/p\u003e\u003cp\u003eTechnical performance parameters include a maximum head of 117.5 m and delivery rates scaling up to 1216 L\/Min through its its 125 mm discharge outlet. Power is supplied by an 18.5 kW motor drawing 38.5 Amps of rated current from a 415v three-phase supply. Performance is maintained through the hydraulic geometry rotating at 2900 rpm for efficient lifting in borehole environments. All performance data is verified based on clean water with a density of 1.0 kg\/dm³.\u003c\/p\u003e\u003cp\u003eConstruction utilizes high-grade cast AISI 316 Stainless Steel for wetted parts including the suction casing, delivery head, and diffusers. This variant is equipped with a Duplex Stainless Steel motor for resistance in specific water environments encountered in borehole wells. The assembly processes water containing suspended sand levels reaching 100 g\/m³ and is rated for temperatures up to 25°C. A duplex stainless steel pump shaft is fabricated to manage the generated torque of five stages.\u003c\/p\u003e\u003cp\u003eRated for immersion depths of 350 meters, the unit features a maximum diameter of 198 mm including cable protection covers. A stainless steel non-return valve with an integrated spring is built into the assembly to prevent reverse rotation and backflow during shutdown. Internal clearance is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft assembly. This electric pump 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\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\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 duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.\u003c\/li\u003e\n\u003cli\u003eMechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.\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":51004072788215,"sku":"ZN855-05\/3A-3R","price":35043.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855053a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098070","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855053a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
