The system combines a Grundfos JP self-priming pump with a PM1 pressure manager, enabling automatic start and stop operation based on water demand.\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 long service life. The integrated ejector design allows efficient self-priming and stable performance when handling air-liquid mixtures during start-up.\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. It achieves a maximum head of 42 metres at shut-off conditions. Based on the performance curve shown on page 3, the unit delivers usable domestic flow across typical pressure ranges and supports a suction lift of up to 8 metres.\u003c\/p\u003e\n\n\u003cp\u003eThe system 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 PM1 controller starts the pump at 1.5 bar and ensures continuous operation while water is being consumed. It includes dry-run protection, anti-cycling functionality, and an integrated non-return valve for reliable system performance.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic Operation via PM1 controller with demand-based start and stop\u003c\/li\u003e\n\u003cli\u003eStart Pressure of 1.5 bar ensures consistent system activation\u003c\/li\u003e\n\u003cli\u003eDry-Run Protection prevents pump damage during water shortage\u003c\/li\u003e\n\u003cli\u003eAnti-Cycling Function avoids frequent start\/stop in leakage conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated Non-Return Valve prevents backflow in the system\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 operation\u003c\/li\u003e\n\u003cli\u003eThermal Protection safeguards motor from overheating\u003c\/li\u003e\n\u003cli\u003eLow Noise Operation with sealed grease-for-life bearings\u003c\/li\u003e\n\u003cli\u003eCompact Booster Design for easy installation and operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710921085175,"sku":"99463898","price":590.0,"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_Household_Transfer_with_PM1_Controller.png?v=1777022368","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-jp-3-42-stainless-steel-self-priming-jet-pump-for-household-transfer-with-pm1-controller","provider":"Foundation Pumps","version":"1.0","type":"link"}
