It serves as a solution for intensive water distribution in agricultural and industrial sectors needing high-volume delivery from aquifers. The assembly is compatible with vertical deep-well installation and horizontal mounting provided a minimum inclination is maintained. This model serves as a dedicated tool for sectors requiring reliable head and large flow capacities from deep reservoirs.\u003c\/p\u003e\u003cp\u003eThe unit achieves performance characteristics including a maximum head of 215.6 m and a delivery capacity scaling up to 1333 L\/Min. Powered by a 37 kW motor on a 415v three-phase supply, the unit draws a rated current of 81.8 Amps during continuous duty. The semi-axial flow design achieves nominal flow rates of 55 m³\/hr for efficient movement across the assembly at 2900 rpm. Performance parameters are calculated for clean water with standard density characteristics.\u003c\/p\u003e\u003cp\u003eComponent construction employs cast AISI 316 Stainless Steel for wetted hydraulic parts including the delivery head, suction casing, and diffusers. 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 of 100 g\/m³ through its eight-stage hydraulic configuration. A duplex stainless steel shaft is used to transmit power to the hydraulic end during rotation.\u003c\/p\u003e\u003cp\u003eThis electric pump supports immersion depths of 350 meters and features a non-return valve built into the head to prevent backflow during shutdown. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard 8-inch well casings including motor cable covers. Internal wear surfaces are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes to ensure mechanical alignment and efficiency. The unit is designed for municipal water systems.\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\u003eA duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.\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\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":51004073345271,"sku":"ZN855-08-3S","price":39868.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855083s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098098","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855083s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
