The system combines a Grundfos JP self-priming pump with a pressure switch, pressure gauge, and a vertical diaphragm pressure tank, ensuring consistent and automatic water pressure control.\u003c\/p\u003e\n\n\u003cp\u003eThe integrated pressure tank reduces water hammer in the pipeline and minimizes pump cycling by supplying stored water during low demand conditions. This improves system efficiency and extends pump life. The pressure switch and tank work together to ensure optimal start and stop operation based on water usage.\u003c\/p\u003e\n\n\u003cp\u003eThe pump is constructed with a stainless steel housing (AISI 304) and a composite impeller (PPO-20GF), providing corrosion resistance and long service life. The self-priming design enables the pump to lift water from below-ground sources and handle air-liquid mixtures during start-up for reliable operation.\u003c\/p\u003e\n\n\u003cp\u003eAccording to the technical data, the pump operates at a rated flow of 4 m³\/h with a corresponding head of 41 metres. Based on the performance curve, the unit achieves a maximum head of approximately 47 metres at shut-off conditions 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. The pressure switch is preset with a cut-in pressure of 2.2 bar, enabling reliable automatic operation based on system demand.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eComplete Booster System including pump, pressure switch, gauge, and tank\u003c\/li\u003e\n\u003cli\u003e20 L Vertical Diaphragm Tank reduces water hammer and stabilizes pressure\u003c\/li\u003e\n\u003cli\u003ePreset Cut-In Pressure of 2.2 bar for automatic operation\u003c\/li\u003e\n\u003cli\u003eReduced Pump Cycling using stored water during low consumption\u003c\/li\u003e\n\u003cli\u003eSelf-Priming Capability with suction lift up to 8 m\u003c\/li\u003e\n\u003cli\u003eHandles air-liquid mixtures during priming for reliable start-up\u003c\/li\u003e\n\u003cli\u003eThermal Protection safeguards motor against overheating\u003c\/li\u003e\n\u003cli\u003eAir-Cooled Motor with sealed bearings for quiet operation\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Stainless Steel Construction for durability\u003c\/li\u003e\n\u003cli\u003eStable Automatic Pressure Control for consistent performance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710938321143,"sku":"99463895","price":685.0,"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_Home_Supply_with_Pressure_Tank.png?v=1777023176","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-jp-4-47-stainless-steel-self-priming-jet-pump-for-garden-irrigation-with-pressure-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
