It provides a robust solution for large-scale water extraction in municipal networks and industrial distribution systems requiring head matching. The pump is compatible with vertical borehole setups and horizontal installations with a 3-degree minimum inclination. This model serves as a specialized tool for lifting groundwater while maintaining precise pressure parameters for irrigation.\u003c\/p\u003e\u003cp\u003eThe model achieves performance metrics including a maximum head of 69.3 m and delivery rates of 1216 L\/Min through the 125 mm outlet. For power, the pump uses an 11 kW motor drawing 24.2 Amps of rated current from a 415v three-phase electrical supply. Efficiency is maintained through precise hydraulic geometry rotating at 2900 rpm for efficient lifting in borehole environments. All technical specifications are verified based on liquids with a density of 1.0 kg\/dm³.\u003c\/p\u003e\u003cp\u003eMaterial integrity is ensured through the use of cast AISI 316 Stainless Steel for the pump body, diffusers, and delivery head. This variant is equipped with a Duplex Stainless Steel motor, providing enhanced material performance in aggressive water conditions. The construction handles liquids containing suspended sand levels of 100 g\/m³ and is rated for temperatures up to 25°C. A duplex stainless steel shaft is utilized to handle mechanical stresses during rotation.\u003c\/p\u003e\u003cp\u003eThe unit is rated for an immersion depth limit of 350 meters and maintains a maximum overall diameter of 198 mm including cable 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. 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\u003eInternal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.\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\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\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\u003eEPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51004072493303,"sku":"ZN855-03\/2A-3R","price":28652.14,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855032a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098050","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855032a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
