The Calpeda NGXM 4\/22 combines high-flow hydraulic performance with self-priming jet pump operation, making it suitable for water circulation duties, garden distribution systems, and above-ground transfer arrangements.\u003c\/p\u003e\n\n\u003cp\u003eProducing flow rates up to 140 L\/Min with maximum head reaching 34.8 m, the pump supports efficient clean water movement across irrigation layouts, washing stations, and pressure-assisted supply systems. Its integrated 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\u003eHydraulic stability is enhanced through an exclusive diffuser geometry paired with an integrated flow control device that assists in minimizing turbulence and lowering running noise. Internal air evacuation around the mechanical seal also contributes to operational reliability by helping reduce seal stress during temporary abnormal suction conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe compact close-coupled construction simplifies installation where available space is restricted while supporting retrofit suitability across existing systems. Both the casing and casing cover are manufactured from AISI 304 stainless steel for corrosion resistance, while the brass impeller supports durable hydraulic efficiency across demanding clean water applications.\u003c\/p\u003e\n\n\u003cp\u003eSingle-phase 230V operation includes integrated thermal motor protection together with IP54 enclosure protection and Class F insulation. Continuous-duty operation is supported for liquid temperatures up to 35°C with maximum permissible casing pressure reaching 8 bar.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eSelf-priming jet pump with integrated ejector system\u003c\/li\u003e\n\u003cli\u003eHigh-flow hydraulic performance up to 140 L\/Min\u003c\/li\u003e\n\u003cli\u003eSuction lift capability up to 9 m for shallow-well duties\u003c\/li\u003e\n\u003cli\u003eBrass impeller supporting durable clean water operation\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 running noise\u003c\/li\u003e\n\u003cli\u003eInternal air evacuation improving mechanical seal reliability\u003c\/li\u003e\n\u003cli\u003eCompact close-coupled construction simplifying installation\u003c\/li\u003e\n\u003cli\u003eIP54 motor protection with Class F insulation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50753122926839,"sku":"NGXM 4\/22","price":1569.87,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-ngxm-4-22-stainless-steel-self-priming-jet-pump-for-water-circulation-with-brass-impeller.png?v=1778217967","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-ngxm-4-22-stainless-steel-self-priming-jet-pump-for-water-circulation-with-brass-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
