Operating this wet end requires secure coupling with a compatible 11 kW electric motor of the appropriate power rating. Designed for secure installation inside standard 6-inch deep wells, the assembly operates inside standard casings. It is suitable for groundwater supply and irrigation systems, municipal supply lines, and agricultural distribution projects.\u003c\/p\u003e\u003cp\u003eTo support long-term physical stability during operation, the structural sleeve and discharge head are engineered from cast AISI 316 Stainless Steel. The multi-stage centrifugal hydraulic assembly consists of 9 stages, each incorporating an AISI 316L stainless steel radial impeller. The integrated radial impellers are designed to limit abrasive wear from sand particles, supporting water containing up to 100 g\/m³ of suspended sand.\u003c\/p\u003e\u003cp\u003eOnce paired with its designated 11 kW electric motor (nominal current rating of 24.2 Amps), the coupled assembly achieves up to 92.7 m maximum head. This multi-stage hydraulic wet end generates a maximum flow of 1,000 L\/Min through its Rp 80 mm threaded connection. All performance parameters are in accordance with manufacturer technical specifications.\u003c\/p\u003e\u003cp\u003eThe pump has a maximum external diameter of 142 mm for installation inside standard 6-inch borehole wells. Maximum pump immersion depth is 300 m when used with C4S motors and 350 m when used with L6W motors. The lower support bracket incorporates a standard 6\" NEMA-compliant mount for simple mechanical motor integration. Safe coupling requires correct mechanical alignment of the pump shaft and the motor shaft during mechanical coupling.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eConstructed entirely from AISI 316 Stainless Steel for corrosion protection and structural durability.\u003c\/li\u003e\n\u003cli\u003eEquipped with 9 multi-stage radial centrifugal impellers manufactured from AISI 316L stainless steel.\u003c\/li\u003e\n\u003cli\u003eIncludes an integrated spring-loaded AISI 316 non-return valve in the discharge head to prevent backflow and maintain system pressure.\u003c\/li\u003e\n\u003cli\u003eFeatures a high-strength Duplex Stainless Steel pump shaft and sleeves.\u003c\/li\u003e\n\u003cli\u003eEquipped with a standard 6\" NEMA-compliant motor support bracket and coupling for easy motor integration.\u003c\/li\u003e\n\u003cli\u003eErP\/Ecodesign compliant with a Minimum Efficiency Index (MEI) of 0.40 or higher, optimizing energy performance.\u003c\/li\u003e\n\u003cli\u003eDesigned with a compact 142 mm maximum external diameter for secure installation inside 6-inch deep well boreholes.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51068700000503,"sku":"ZN646\/9","price":8959.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn646-9-stainless-steel-deep-well-6-inch-submersible-bore-pump-wet-end-only-with-radial-flow-impeller.png?v=1787739549","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn646-9-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
