With strong suction capability, it is ideal for drawing water from wells, ground tanks, and below-ground sources where the pump is installed above the water level.\u003c\/p\u003e\n\n\u003cp\u003eThe pump is constructed with a stainless steel housing (AISI 304) and a composite impeller (PPO-20GF), providing excellent corrosion resistance and durability. The integrated ejector with guide vanes ensures efficient self-priming performance and stable operation, even when handling air-liquid mixtures during the priming phase.\u003c\/p\u003e\n\n\u003cp\u003eAccording to the performance data, the pump operates at a rated flow of 4 m³\/h with a corresponding head of 41 metres. It achieves a maximum head of 44.5 metres at shut-off conditions. Based on the performance curve, the pump delivers practical flow across typical domestic pressure ranges and supports a suction lift of up to 8 metres.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is powered by a 0.56 kW electric motor operating on a 1 x 230 V, 50 Hz supply, with a rated current of 3.8 Amps. It includes built-in thermal protection to prevent overheating and features sealed, grease-for-life ball bearings for quiet and maintenance-free operation.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eSelf-Priming Design with built-in ejector for efficient suction performance\u003c\/li\u003e\n\u003cli\u003eCapable of handling air-liquid mixtures during priming cycle\u003c\/li\u003e\n\u003cli\u003eIntegrated Thermal Protection to prevent motor overheating\u003c\/li\u003e\n\u003cli\u003eAir-Cooled Motor Design for stable and efficient operation\u003c\/li\u003e\n\u003cli\u003eSealed Bearings ensure low noise and maintenance-free performance\u003c\/li\u003e\n\u003cli\u003eCompact Portable Design with integrated lifting handle\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Construction using stainless steel and composite materials\u003c\/li\u003e\n\u003cli\u003eStable Operation even under variable suction conditions\u003c\/li\u003e\n\u003cli\u003eDesigned for installation above water source level\u003c\/li\u003e\n\u003cli\u003eSuitable for continuous long-term operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710897361143,"sku":"99458783","price":515.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-jp-4-47-stainless-steel-self-priming-jet-pump-for-domestic-supply-single-impeller.png?v=1777020969","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-jp-4-47-stainless-steel-self-priming-jet-pump-for-domestic-supply-single-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
