The integrated ejector arrangement supports dependable suction lift operation for irrigation supply, utility washdown systems, and network pressure support applications.\u003c\/p\u003e\n\n\u003cp\u003ePerformance capability reaches 59 m maximum head with flow rates extending to 9.5 m³\/h, delivering balanced hydraulic operation between pressure generation and increased water movement. The pump operates through a three-phase 400V induction motor rated at 2.2 kW with operating current of 5.3 A while maintaining approximately 2900 rpm operating speed for continuous-duty service.\u003c\/p\u003e\n\n\u003cp\u003eHydraulic circulation is maintained through a brass impeller arrangement supporting stable transfer of clean liquids and slightly dirty surface water. Noryl diffuser and nozzle elements assist controlled liquid acceleration within the self-priming system while supporting dependable suction-assisted hydraulic performance during varying flow demand.\u003c\/p\u003e\n\n\u003cp\u003eThe pump casing, casing cover, and diffuser plate utilize cast iron construction for structural integrity under elevated operating pressure conditions. A carbon ceramic mechanical seal with NBR elastomer support components assists leakage control, while the motor assembly integrates class F insulation and IP54 environmental protection. Maximum liquid temperature reaches 40°C with permissible working pressure capability up to 10 bar.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated ejector arrangement supporting self-priming shallow well operation\u003c\/li\u003e\n\u003cli\u003eBrass impeller arrangement supporting stable high-volume hydraulic transfer\u003c\/li\u003e\n\u003cli\u003eNoryl PPO-GF20 diffuser and nozzle assembly assisting flow stabilization\u003c\/li\u003e\n\u003cli\u003eClose-coupled pump and motor construction minimizing alignment requirements\u003c\/li\u003e\n\u003cli\u003eThree-phase motor configuration designed for continuous-duty applications\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic sealing system with NBR elastomer support materials\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor enclosure with IP54 protection specification\u003c\/li\u003e\n\u003cli\u003eCast iron hydraulic structure supporting elevated working pressure operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50762189406455,"sku":"NG 7\/22","price":1486.35,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-ng-7-22-cast-iron-close-coupled-jet-pump-for-irrigation-supply-with-brass-impeller.png?v=1778556132","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-ng-7-22-cast-iron-close-coupled-jet-pump-for-irrigation-supply-with-brass-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
