It is essential to pair this standalone pump end with a compatible 30 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 water transfer and pressure boosting 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 31 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 30 kW electric motor (nominal current rating of 61.7 Amps), the coupled assembly achieves up to 414 m maximum head. This multi-stage hydraulic wet end generates a maximum flow of 500 L\/Min through its Rp 65 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 31 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":51068699050231,"sku":"ZN622\/31","price":17950.68,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-zn622-31-stainless-steel-deep-well-6-submersible-pump-wet-end-only-radial-flow-impeller.png?v=1787739503","url":"https:\/\/foundationpumps.com.au\/products\/lowara-zn622-31-stainless-steel-deep-well-6-submersible-pump-wet-end-only-radial-flow-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
