It serves as an efficient tool for moving clean water from deep boreholes to surface distribution networks or industrial storage facilities. The unit supports vertical well installation or horizontal deployment where the system layout allows for a 3-degree minimum incline. This model provides high head potential while maintaining large flow capacities from aquifers.\u003c\/p\u003e\u003cp\u003eTechnical parameters include a maximum total head of 134.8 m and peak flow rates of 1333 L\/Min through the 125 mm discharge head. For power, the unit is equipped with a 22 kW motor drawing a rated current of 47.3 Amps from a 415v three-phase supply. Efficiency occurs through a semi-axial hydraulic arrangement designed for efficient lifting at a rotation speed of 2900 rpm. Performance data is verified for clean water based on standard density and viscosity characteristics.\u003c\/p\u003e\u003cp\u003eMaterial construction features cast AISI 316 Stainless Steel for wetted parts including the delivery head, suction support, and diffusers. This variant is equipped with a Duplex Stainless Steel motor, providing durability in aggressive water conditions found in deep wells. The assembly processes water containing suspended sand concentrations up to 100 g\/m³ and is rated for temperatures of 25°C. A duplex stainless steel shaft is utilized to transmit power to the five hydraulic stages.\u003c\/p\u003e\u003cp\u003eThe unit is rated for an immersion depth of 350 meters and maintains a maximum overall diameter of 198 mm including cable protection covers. A non-return valve with an integrated spring is situated in the delivery outlet to protect against reverse rotation and surges. Internal tolerances 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 industrial distribution projects.\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\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\u003eA duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.\u003c\/li\u003e\n\u003cli\u003eStainless steel cable covers provide mechanical protection for motor power leads along the casing.\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\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51004072919287,"sku":"ZN855-05-3R","price":36117.18,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855053r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098077","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855053r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
