The assembly provides significant head potential for lifting water to surface storage points or industrial distribution networks. The unit is compatible with vertical installations in borehole wells and horizontal deployment provided a minimum inclination is maintained. This model serves as an ideal solution for large-scale agricultural and municipal distribution.\u003c\/p\u003e\u003cp\u003eOperating characteristics for this model include a maximum total head of 80.9 m and delivery capacity reaching 1333 L\/Min via the 125 mm discharge outlet. The power section utilizes a 15 kW motor drawing 32.1 Amps of rated current from a 415v three-phase supply. Performance is maintained at a rotation speed of 2900 rpm for liquids with standard density and kinematic viscosity. Efficiency is achieved through precise hydraulic geometry designed for large-volume lifting.\u003c\/p\u003e\u003cp\u003eConstruction utilizes high-grade cast AISI 316 Stainless Steel for the suction support, delivery casing, and diffusers. This variant is equipped with a Duplex Stainless Steel motor, providing durability in specific borehole environments found in deep wells. The assembly processes water containing suspended sand levels up to 100 g\/m³ and is rated for temperatures up to 25°C. The internal pump shaft is made of duplex stainless steel to manage mechanical stress during rotation.\u003c\/p\u003e\u003cp\u003eThe unit handles immersion depths of 350 meters and features a 198 mm maximum overall diameter including cable protection covers. A built-in non-return valve with a stainless steel spring is situated in the delivery head to prevent backflow and reverse rotation. Internal tolerances are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the shaft alignment. The pump is designed for continuous duty cycles in municipal infrastructure projects.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\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\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":51004072558839,"sku":"ZN855-03-3R","price":29616.13,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855033r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098054","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855033r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
