It provides high pressure and flow for agricultural and municipal distribution projects requiring head potential from borehole sites. The unit supports vertical well installation or horizontal deployment where the layout allows the motor to be in the lowest position. This model serves as an efficient extraction tool for industrial water supply projects needing specific lift parameters.\u003c\/p\u003e\u003cp\u003eTechnical parameters include a maximum head of 204.1 m and delivery capacity up to 1216 L\/Min through its 125 mm discharge outlet. Electrical power is supplied by a 37 kW motor drawing 81.8 Amps of rated current from a 415v three-phase supply. Delivery efficiency occurs through a semi-axial hydraulic arrangement designed for deep borehole service at a rotation speed of 2900 rpm. All performance data is verified based on liquids with standard clean water density.\u003c\/p\u003e\u003cp\u003eMaterial integrity is ensured through cast AISI 316 Stainless Steel for components including the delivery casing, suction casing, and diffusers. This variant features a Duplex Stainless Steel motor, providing resistance in aggressive borehole media found in deep wells. The assembly processes water containing suspended sand concentrations up to 100 g\/m³ and is rated for temperatures up to 25°C. The internal duplex stainless steel shaft manages the generated mechanical torque during rotation.\u003c\/p\u003e\u003cp\u003eRated for immersion depths of 350 meters, the unit features a maximum overall diameter of 198 mm including motor cable protection covers. A non-return valve with an integrated stainless steel spring is built into the assembly to prevent reverse rotation and surges. Internal clearances are maintained 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.\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\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\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":51004073312503,"sku":"ZN855-08\/2A-3R","price":48562.03,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855082a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098096","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855082a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
