It serves as a solution for irrigation and industrial water distribution where extraction from deep underground sources is necessary. The pump supports vertical mounting in boreholes or horizontal installation in systems with a minimum inclination of 3 degrees. This model provides high volume delivery while matching specific head parameters required by agricultural networks.\u003c\/p\u003e\u003cp\u003eOperating parameters for this configuration include a 7.5 kW motor power rating at 415v, drawing a rated current of 17 Amps. The system achieving a maximum total head of 42.9 m and a peak flow capacity of 1216 L\/Min through the 125 mm discharge head. Performance metrics are maintained at a rotation speed of 2900 rpm for liquids with standard density and kinematic viscosity. This configuration utilizes a semi-axial hydraulic design to maintain delivery efficiency.\u003c\/p\u003e\u003cp\u003eMaterial construction features cast AISI 316 Stainless Steel for the wet end components including the diffusers and suction casing. This variant is equipped with a Duplex Stainless Steel motor for resistance in specific water environments encountered in borehole wells. The unit is rated for maximum liquid temperatures of 25°C and can operate in water containing up to 100 g\/m³ of suspended sand. The internal shaft is fabricated from duplex stainless steel to ensure mechanical stability.\u003c\/p\u003e\u003cp\u003eRatings include a 350-meter maximum immersion depth and a 198 mm overall diameter including cable protections. An integrated non-return valve with a stainless steel spring is situated in the delivery outlet to protect against reverse rotation. Internal tolerances are managed by technopolymer POM-C wear rings and EPDM 70 bearing bushes supporting the duplex shaft. This electric pump is designed for continuous duty cycles in municipal infrastructure and large-scale agricultural distribution.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThe integrated non-return valve features a stainless steel spring to prevent fluid backflow.\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\u003cli\u003eStainless steel cable covers provide mechanical protection for motor power leads along the casing.\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\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":51004072296695,"sku":"ZN855-02\/2A-3R","price":26016.38,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn855022a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller.png?v=1786098039","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn855022a3r-stainless-steel-deep-well-8-inch-submersible-bore-pump-semi-axial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
