The system includes a Grundfos JP self-priming pump, a pressure switch, pressure gauge, and a vertical diaphragm pressure tank, delivering stable and automatic 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. The pressure switch and tank work together to ensure efficient start and stop operation, improving system performance and extending pump life.\u003c\/p\u003e\n\n\u003cp\u003eThe pump is constructed with a stainless steel housing (AISI 304) and a composite impeller (PPO-20GF), ensuring corrosion resistance and durability. The self-priming design allows the pump to handle air-liquid mixtures during start-up and supports suction lift from below-ground water sources.\u003c\/p\u003e\n\n\u003cp\u003eAccording to the technical data, the pump operates at a rated flow of 3 m³\/h with a corresponding head of 36.5 metres. From the performance curve, the unit achieves a maximum head of approximately 42 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 0.45 kW electric motor operating on a 1 x 230 V, 50 Hz supply, with a rated current of 3.1 Amps. The pressure switch is preset with a cut-in pressure of 2.2 bar, ensuring 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 with pump, pressure switch, gauge, and diaphragm tank\u003c\/li\u003e\n\u003cli\u003e20 L Vertical Pressure 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 tank water during low demand\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 performance\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Stainless Steel Construction for durability\u003c\/li\u003e\n\u003cli\u003eAutomatic Pressure Control for consistent household supply\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710935339255,"sku":"99463894","price":650.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/Grundfos_JP_3-42_Stainless_Steel_Self-Priming_Jet_Pump_for_Home_Supply_with_Pressure_Tank.png?v=1777023180","url":"https:\/\/foundationpumps.com.au\/products\/rundfos-jp-3-42-stainless-steel-self-priming-jet-pump-for-home-supply-with-pressure-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
