Its construction in AISI 304 stainless steel and the incorporation of a non-return valve ensure reliability, protection of the delivery line, and long service life with clean water. This hydraulic unit is optimized to work with Lorentz ECDRIVE motors from the 1200\/1800 range, reaching up to 4.0 m³\/h and 80 m when configured with the appropriate motor and controller. It is the ideal solution as a replacement, for preventive maintenance, or to assemble a new PU\/PS2 unit based on the C-SJ3-18 platform.\u003c\/p\u003e\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cstrong\u003eC-SJ3-18\u003c\/strong\u003e centrifugal series for 4\" wells, balanced flow\/head performance.\u003c\/li\u003e\n  \u003cli\u003eManufactured in \u003cstrong\u003eAISI 304 stainless steel\u003c\/strong\u003e, corrosion-resistant in clean water.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated non-return valve\u003c\/strong\u003e: prevents column return and water hammer.\u003c\/li\u003e\n  \u003cli\u003eMaximum reference hydraulic efficiency: \u003cstrong\u003eup to 54%\u003c\/strong\u003e with compatible motor.\u003c\/li\u003e\n  \u003cli\u003eLorentz modular architecture that facilitates installation and maintenance.\u003c\/li\u003e\n  \u003cli\u003eHydraulic curve suitable for tanks, gravity irrigation, and medium lines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAdvantages or Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintains original performance as an official replacement compatible with Lorentz motors.\u003c\/li\u003e\n  \u003cli\u003eReduces downtime due to failures thanks to premium materials and robust design.\u003c\/li\u003e\n  \u003cli\u003eGreater hydraulic safety due to its integrated non-return valve.\u003c\/li\u003e\n  \u003cli\u003eStable performance over a wide operating range, optimizing water per solar kWh.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePurpose or Applications\u003c\/h3\u003e\n\u003cp\u003eSuitable for residential and agricultural solar pumping, supply to tanks, transfers, and low\/medium pressure irrigation where a balance between flow (up to 4.0 m³\/h) and head (up to 80 m) is required.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003eHydraulic type\u003c\/td\u003e\n\u003ctd\u003eCentrifugal, C-SJ3-18 series\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMaximum flow\u003c\/td\u003e\n\u003ctd\u003e4.0 m³\/h (with suitable motor\/controller)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMaximum head\u003c\/td\u003e\n\u003ctd\u003e80 m (with suitable motor\/controller)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMax. hydraulic efficiency\u003c\/td\u003e\n\u003ctd\u003eUp to 54%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMaterials\u003c\/td\u003e\n\u003ctd\u003eAISI 304 stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eValve\u003c\/td\u003e\n\u003ctd\u003eIntegrated non-return\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWell diameter\u003c\/td\u003e\n\u003ctd\u003e4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eApprox. head weight\u003c\/td\u003e\n\u003ctd\u003e≈ 6.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibilities\u003c\/h3\u003e\n\u003cp\u003eDirect compatibility with \u003cstrong\u003eLorentz ECDRIVE 1200-C \/ 1800-C\u003c\/strong\u003e motors, with the \u003cstrong\u003ePU1800 C-SJ3-18\u003c\/strong\u003e unit, and with the complete \u003cstrong\u003ePS2-1800 C-SJ3-18\u003c\/strong\u003e system.
