The unit features a configuration compatible with both vertical borehole setups and horizontal pressure boosting stations. This specific model moves large volumes of water from deep underground reservoirs to surface distribution points. It serves as a dedicated extraction tool for irrigation systems and industrial water networks requiring consistent flow rates.\u003c\/p\u003e\u003cp\u003eOperating characteristics for this single-stage configuration include a maximum total head of 27 m and a delivery capacity of 1333 L\/Min. The power section utilizes a 5.5 kW motor drawing 12.7 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 viscosity. These metrics are verified through precise hydraulic geometry designed for deep borehole service.\u003c\/p\u003e\u003cp\u003eMaterial construction utilizes cast AISI 316 Stainless Steel for wetted components including the suction support, diffusers, and impeller. This variant is equipped with a Duplex Stainless Steel motor, providing specific material properties for aggressive media contact. The assembly handles liquids with a maximum temperature of 25°C and processes water containing suspended sand levels of 100 g\/m³. The internal shaft is made of high-grade duplex stainless steel to resist mechanical stress.\u003c\/p\u003e\u003cp\u003eThis electric pump is rated for immersion depths of 350 meters and features a 198 mm maximum overall diameter. A stainless steel non-return valve with an integrated spring is built into the delivery casing to protect the internal components. The system utilizes EPDM bearing bushes and technopolymer wear rings to maintain hydraulic efficiency during continuous duty cycles. The structure is designed for borehole wells where consistent water delivery and high material integrity are 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\u003eThe integrated non-return valve features a stainless steel spring to prevent fluid backflow.\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\u003eMechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.\u003c\/li\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\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51004072231159,"sku":"ZN855-01-3R","price":23394.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855013r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098035","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855013r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
