It serves as an efficient extraction tool for municipal water supply projects and industrial systems needing significant head potential from underground reservoirs. The unit supports vertical borehole installation and horizontal mounting provided a minimum 3-degree incline is maintained. This model provides high head lifting while maintaining high flow rates from underground aquifers.\u003c\/p\u003e\u003cp\u003eTechnical parameters include a maximum head of 188.7 m and a delivery capacity of 1333 L\/Min through the 125 mm discharge head. Powered by a 30 kW motor drawing 63.8 Amps of rated current from a 415v three-phase electrical supply. Peak delivery occurs through a semi-axial hydraulic arrangement designed for deep borehole service at a rotation speed of 2900 rpm. All metrics are validated for clean water based on standard density and viscosity characteristics.\u003c\/p\u003e\u003cp\u003eWet end components such as the impellers, diffusers, and delivery casing are constructed from cast AISI 316 Stainless Steel. This variant features a Duplex Stainless Steel motor, providing resistance in aggressive borehole media found in municipal and industrial wells. The assembly processes water containing suspended sand concentrations up to 100 g\/m³ and is rated for temperatures up to 25°C. A duplex stainless steel shaft is utilized to handle mechanical stresses during rotation.\u003c\/p\u003e\u003cp\u003eRated for immersion depths of 350 meters, the unit features a 198 mm maximum overall diameter making it compatible with standard 8-inch well casings. 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 duplex shaft assembly. This design is intended for continuous industrial and municipal duty tasks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA stainless steel suction strainer excludes large particles from entering the hydraulic stages.\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\u003eEPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.\u003c\/li\u003e\n\u003cli\u003eMechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.\u003c\/li\u003e\n\u003cli\u003eThe integrated non-return valve features a stainless steel spring to prevent fluid backflow.\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":51004073214199,"sku":"ZN855-07-3R","price":44945.45,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855073r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098092","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855073r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
