It is essential to pair this standalone pump end with a compatible 4 kW electric motor for deep-well water supply. The physical structure is designed for standard vertical placement inside standard 6-inch casings. It is suitable for pressure boosting and dewatering networks and water distribution setups.\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 3 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 4 kW electric motor (nominal current rating of 10.2 Amps), the coupled assembly achieves up to 31 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 4\" 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 3 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 4\" 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":51068699803895,"sku":"4ZN646\/3","price":6283.53,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-4zn646-3-stainless-steel-deep-well-6-inch-submersible-bore-pump-wet-end-only-with-radial-flow-impeller.png?v=1787739540","url":"https:\/\/foundationpumps.com.au\/products\/lowara-4zn646-3-stainless-steel-deep-well-6-submersible-bore-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
