The Calpeda NGX 4\/22 is configured for storage tank refill duties, high-flow clean water transfer, and irrigation supply applications operating from above-ground installations.\u003c\/p\u003e\n\n\u003cp\u003eThe pump delivers flow rates up to 140 L\/Min with maximum head reaching 34.8 m, supporting efficient water movement across tank circulation systems, washing arrangements, and pressure-assisted transfer duties. A built-in ejector system assists automatic priming performance while maintaining suction lift capability up to 9 m during shallow-well operation.\u003c\/p\u003e\n\n\u003cp\u003eTo improve hydraulic stability during continuous-duty operation, Calpeda incorporates an exclusive diffuser geometry together with an integrated flow control device that helps reduce turbulence and lower operational noise. Internal air evacuation around the mechanical seal also assists in minimizing seal stress caused by temporary abnormal suction conditions.\u003c\/p\u003e\n\n\u003cp\u003eAISI 304 stainless steel construction across both the casing and casing cover supports corrosion resistance for demanding clean water duties, while the brass impeller contributes to durable hydraulic efficiency under higher-flow operating conditions. Compact close-coupled construction also simplifies installation where available space is restricted.\u003c\/p\u003e\n\n\u003cp\u003eThe three-phase motor operates on 400V power supply with IP54 enclosure protection and Class F insulation. Continuous-duty operation is suitable for liquid temperatures up to 35°C with maximum permissible casing pressure reaching 8 bar.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-in ejector supporting rapid self-priming operation\u003c\/li\u003e\n\u003cli\u003eSuitable for storage tank refill and transfer duties\u003c\/li\u003e\n\u003cli\u003eUp to 9 m suction lift capability\u003c\/li\u003e\n\u003cli\u003eBrass impeller supporting durable hydraulic efficiency\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing and casing cover\u003c\/li\u003e\n\u003cli\u003eExclusive diffuser geometry assisting stable hydraulic flow\u003c\/li\u003e\n\u003cli\u003eIntegrated flow control device helping reduce operational noise\u003c\/li\u003e\n\u003cli\u003eInternal air evacuation system improving seal reliability\u003c\/li\u003e\n\u003cli\u003eCompact close-coupled configuration simplifying installation\u003c\/li\u003e\n\u003cli\u003eThree-phase motor with IP54 protection and Class F insulation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50753429569783,"sku":"NGX 4\/22","price":1528.73,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-ngx-4-22-stainless-steel-self-priming-jet-pump-for-storage-tank-refill-with-brass-impeller.png?v=1778226353","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-ngx-4-22-stainless-steel-self-priming-jet-pump-for-storage-tank-refill-with-brass-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
