The integrated ejector configuration supports stable suction performance across agricultural supply networks, pressure boosting installations, and utility water circulation duties.\u003c\/p\u003e\n\n\u003cp\u003eMaximum hydraulic head reaches 74.5 m while flow output extends to 6.5 m³\/h, supporting efficient pressure delivery across medium-to-large water distribution systems. Power is supplied through a three-phase 400V induction motor rated at 2.2 kW with operating current of 5.3 A while maintaining operating speed near 2900 rpm during continuous-duty service.\u003c\/p\u003e\n\n\u003cp\u003eFlow transfer is managed through a brass impeller arrangement supporting smooth hydraulic movement and reliable jet-assisted circulation. Noryl diffuser and nozzle sections contribute to stable internal flow control while supporting operation with clean liquids and slightly dirty surface water under varying operating demand.\u003c\/p\u003e\n\n\u003cp\u003eCast iron construction across the hydraulic body, casing cover, and diffuser plate contributes structural durability during prolonged elevated-pressure operation. The assembly incorporates a carbon ceramic mechanical seal with NBR elastomer elements together with class F motor insulation and IP54 protection. Operating capability supports liquid temperatures up to 40°C with maximum permissible working pressure reaching 10 bar.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eSelf-priming jet configuration with integrated shallow well ejector system\u003c\/li\u003e\n\u003cli\u003eBrass impeller arrangement supporting balanced pressure and flow performance\u003c\/li\u003e\n\u003cli\u003eNoryl PPO-GF20 hydraulic diffuser and nozzle construction\u003c\/li\u003e\n\u003cli\u003eClose-coupled pump arrangement reducing installation footprint requirements\u003c\/li\u003e\n\u003cli\u003eThree-phase induction motor supporting continuous-duty operating cycles\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic seal faces with NBR elastomer sealing support components\u003c\/li\u003e\n\u003cli\u003eIP54 protected motor housing combined with class F insulation system\u003c\/li\u003e\n\u003cli\u003eCast iron hydraulic structure supporting elevated pressure stability\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50762189308151,"sku":"NG 7\/18","price":1830.05,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-ng-7-18-cast-iron-self-priming-jet-pump-for-clean-liquid-transfer-with-brass-impeller.png?v=1778556094","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-ng-7-18-cast-iron-self-priming-jet-pump-for-clean-liquid-transfer-with-brass-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
