It integrates the high-efficiency ECDrive 1800-HRE brushless motor and the HRE-03H helical hydraulics in AISI 304\/316 stainless steel with an integrated check valve. It is capable of reaching up to 240 m in height with a reference flow rate of 0.43 m³\/h, making it an ideal option for very deep wells, high-elevation tanks, and long pipelines. As a PU version, it includes pump + motor, but \u003cstrong\u003edoes not include a controller\u003c\/strong\u003e; it must be combined with a compatible Lorentz controller for operation with solar energy.\u003c\/p\u003e\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cstrong\u003eHelical\u003c\/strong\u003e HRE-03H hydraulics optimized for high pressure with controlled flow.\u003c\/li\u003e\n  \u003cli\u003eReference flow rate \u003cstrong\u003e0.43 m³\/h\u003c\/strong\u003e and lift up to \u003cstrong\u003e240 m\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003eECDrive 1800-HRE motor (~1.7 kW), brushless, \u003cstrong\u003eIP68\u003c\/strong\u003e, maintenance-free.\u003c\/li\u003e\n  \u003cli\u003eRobust construction in \u003cstrong\u003eAISI 304\/316\u003c\/strong\u003e and integrated \u003cstrong\u003echeck valve\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003eLorentz ecosystem: spare parts available and compatibility with high-power PS2 controllers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAdvantages or Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAbility to extract water from extreme depths with optimized solar consumption.\u003c\/li\u003e\n  \u003cli\u003eReduced operating cost due to the high-efficiency brushless motor and high-performance hydraulics.\u003c\/li\u003e\n  \u003cli\u003eProtection of the installation (column and pipes) thanks to the integrated check valve.\u003c\/li\u003e\n  \u003cli\u003eSimple installation and service thanks to the modular design and availability of spare parts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePurpose or Applications\u003c\/h3\u003e\n\u003cp\u003eWater extraction in very deep wells, high-elevation tanks, drip irrigation on steep slopes, and livestock in remote areas.
