The reduced impeller configuration is optimized for lifting groundwater from deep underground reservoirs to surface distribution points. The unit supports vertical well installation or horizontal deployment provided the motor remains in the lowest position during service. This model serves as an efficient extraction tool for municipal water supply projects requiring significant lift potential.\u003c\/p\u003e\u003cp\u003eHydraulic characteristics for this configuration include a maximum head of 96.3 m and delivery rates scaling up to 1216 L\/Min. The electrical section consists of a 15 kW motor with a rated current of 32.1 Amps from a 415v three-phase supply. Efficiency is achieved through a semi-axial hydraulic arrangement rotating at 2900 rpm for efficient lifting in borehole environments. All technical performance values are verified for liquids with standard density and kinematic viscosity.\u003c\/p\u003e\u003cp\u003eMaterial construction features cast AISI 316 Stainless Steel for the wetted components including the suction casing and diffusers. This variant is equipped with a Duplex Stainless Steel motor, providing enhanced material performance in aggressive borehole media. The system handles liquids with suspended sand concentrations up to 100 g\/m³ and is rated for temperatures of 25°C. A duplex stainless steel pump shaft is fabricated to withstand the mechanical stresses of four hydraulic stages.\u003c\/p\u003e\u003cp\u003eRatings include a 350-meter maximum immersion depth and a 198 mm overall diameter including cable protection covers. A non-return valve with an integrated stainless steel spring is built into the assembly to prevent reverse rotation and backflow. Internal wear surfaces are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft alignment. This electric pump is designed for continuous duty cycles in municipal infrastructure and industrial projects.\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\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\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\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":51004072657143,"sku":"ZN855-04\/2A-3R","price":32041.52,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855042a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098062","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855042a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
