The system combines a Grundfos JP self-priming pump with a PM1 pressure manager, providing 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 enables efficient self-priming and allows the pump to handle air-liquid mixtures during priming for stable 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 46 metres. From the performance curve, the unit achieves a maximum head of approximately 50 metres at shut-off conditions and delivers practical usable flow across domestic pressure ranges. The system supports a suction lift of up to 8 metres.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is powered by a 0.75 kW electric motor operating on a 1 x 230 V, 50 Hz supply, with a rated current of 5.1 Amps. The PM1 controller starts the pump at 1.5 bar and keeps it running as long as there is flow. It includes dry-run protection, anti-cycling functionality, and an integrated non-return valve for reliable and safe operation.\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 activation\u003c\/li\u003e\n\u003cli\u003eDry-Run Protection prevents pump damage during water shortage\u003c\/li\u003e\n\u003cli\u003eAnti-Cycling Function reduces unnecessary operation during 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 stable performance\u003c\/li\u003e\n\u003cli\u003eThermal Protection protects motor from overheating\u003c\/li\u003e\n\u003cli\u003eAir-Cooled Motor with sealed bearings for quiet operation\u003c\/li\u003e\n\u003cli\u003eCompact Booster Design for easy installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710929211639,"sku":"99463900","price":670.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-jp-4-54-stainless-steel-self-priming-jet-pump-for-tank-filling-single-impeller-with-pm1-controller.png?v=1777022738","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-jp-4-54-stainless-steel-self-priming-jet-pump-for-tank-filling-single-impeller-with-pm1-controller","provider":"Foundation Pumps","version":"1.0","type":"link"}
