It combines the centrifugal hydraulic body PE C-SJ17-2, made of AISI 304 stainless steel with an integrated check valve, and a high-efficiency, low-maintenance ECDRIVE submersible motor. With a flow rate of up to 26 m³\/h and a maximum head of 16 m, it is a robust, modular, and reliable solution for agricultural irrigation, reservoir filling, and water transfer in operations that require high flow without complexity. This version is \u003cstrong\u003ePU (does not include controller)\u003c\/strong\u003e, intended to be integrated with Lorentz controllers of the same platform, which provide MPPT, protections, and automation with probes and float switches.\u003c\/p\u003e\n\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum flow rate of \u003cstrong\u003e26 m³\/h\u003c\/strong\u003e and maximum head of \u003cstrong\u003e16 m\u003c\/strong\u003e in 6\" wells.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eCentrifugal PE C-SJ17-2\u003c\/strong\u003e hydraulics with integrated check valve and excellent performance.\u003c\/li\u003e\n  \u003cli\u003eECDRIVE 1200\/1800-C motor, brushless, \u003cstrong\u003eIP68\u003c\/strong\u003e, water-lubricated; nominal power approximately \u003cstrong\u003e1.7 kW\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003eConstruction in \u003cstrong\u003eAISI 304 stainless steel\u003c\/strong\u003e for maximum durability in clean water.\u003c\/li\u003e\n  \u003cli\u003eLorentz modular architecture: easy assembly, fast service, and availability of original spare parts.\u003c\/li\u003e\n  \u003cli\u003eSilent operation and minimal maintenance, ideal for remote environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAdvantages or Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh flow with low head: rapid filling of tanks and reservoirs without oversizing the installation.\u003c\/li\u003e\n  \u003cli\u003eLong-term reliability thanks to stainless materials, brushless motor, and sealed design.\u003c\/li\u003e\n  \u003cli\u003eIntegrated check valve that protects the water column and prevents unwanted backflow or emptying.\u003c\/li\u003e\n  \u003cli\u003eScalability: by adding a Lorentz controller you obtain MPPT, protections, and level-based automation.\u003c\/li\u003e\n  \u003cli\u003eSimple integration into new solar systems or as a replacement pump unit in existing installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePurpose or Applications\u003c\/h3\u003e\n\u003cp\u003eSuitable for gravity or low-pressure sprinkler irrigation, transfers between tanks, reservoir refilling, and supply for agricultural and livestock operations.
