It is built for extracting clean water from deep boreholes where specific pressure matching is required for distribution networks. The unit is suitable for vertical well installation or horizontal deployment provided a 3-degree inclination is maintained. This configuration serving sectors needing consistent high-volume water lifting while matching specific lift parameters.\u003c\/p\u003e\u003cp\u003eHydraulic characteristics for this model include a maximum head of 69.3 m and a delivery rate reaching 1216 L\/Min through its 125 mm discharge outlet. The electrical section features an 11 kW motor operating on a 415v three-phase supply with a rated current of 24.2 Amps. Performance metrics are maintained through a semi-axial hydraulic flow design achieving high efficiency in water transfer tasks. These values are verified for liquids with a density of 1.0 kg\/dm³.\u003c\/p\u003e\u003cp\u003eComponent construction employs cast AISI 316 Stainless Steel for the delivery head, suction support, and internal impellers. The motor is also fabricated from 316 Stainless Steel and is rated for contact with liquids up to 25°C during continuous service. The assembly handles water containing suspended sand levels of 100 g\/m³ through the use of technopolymer POM-C wear rings. A duplex stainless steel shaft and coupling are used to transmit power through the assembly at 2900 rpm.\u003c\/p\u003e\u003cp\u003eThe assembly handles immersion depths of 350 meters and features a 198 mm maximum overall diameter to fit standard 8-inch casings. A non-return valve with a stainless steel spring is built into the delivery casing to protect the pump from reverse flow. Internal clearance is managed by EPDM 70 bearing bushes and technopolymer wear rings supporting the duplex shaft assembly. This design is intended for high-demand municipal and industrial extraction tasks where flow capacity is required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStainless steel cable covers provide mechanical protection for motor power leads along the casing.\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\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\u003eInternal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51004072460535,"sku":"ZN855-03\/2A-3S","price":20038.92,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855032a3s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098048","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855032a3s-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
