The two-stage configuration with one reduced impeller is intended to handle demanding borehole lifting tasks while maintaining specific hydraulic parameters. The system is suitable for vertical well installation or horizontal deployment where layout requires a low-profile incline. This unit serves as a robust solution for irrigation and livestock needs from underground sources.\u003c\/p\u003e\u003cp\u003eThe system achieving a maximum head of 48.1 m and delivery rates scaling up to 1216 L\/Min through its its 125 mm discharge outlet. Power is delivered by an 11 kW motor operating on 415v with a rated current draw of 24.2 Amps during service. The semi-axial flow design is used to move high volumes of water efficiently at a rotation speed of 2900 rpm. All performance values are calculated for liquids with a density of 1.0 kg\/dm³.\u003c\/p\u003e\u003cp\u003eMaterial construction features cast AISI 316 Stainless Steel for wetted parts including the impellers, diffusers, and delivery head. This model 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. The internal pump shaft is made of duplex stainless steel to resist mechanical stress.\u003c\/p\u003e\u003cp\u003eThe system is rated for a maximum immersion depth of 350 meters and features a 198 mm overall diameter including cable covers. A built-in non-return valve with a stainless steel spring protects the internal components from backflow and pressure surges. Internal wear is managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes which support the shaft assembly. The pump is intended for continuous industrial duty in large-scale water 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\u003eMechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.\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\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":51004072362231,"sku":"ZN855-02\/1A-3R","price":26218.34,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855021a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098043","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855021a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
