Specifications
Product Description
The Lorentz PU1800 C-SJ1-25 Solar Submersible Pump is a professional pump unit designed to supply water at great heights with maximum efficiency and minimal maintenance. It combines the ECDRIVE 1200/1800-C brushless, sealed, water-filled motor (IP68) with the PE C-SJ1-25 centrifugal hydraulic body made of AISI 304 stainless steel and equipped with a check valve. This version is delivered without a controller, making it perfect for integration with an existing Lorentz PS2-1800 controller or for configuring a custom system. Under optimal conditions, the set with its controller achieves up to 3.0 m³/h flow rate and 140 m head, making it ideal for deep wells, elevated tanks, and pipelines with significant elevation differences.
Main Features
- Submersible unit with ECDRIVE 1200/1800-C brushless motor, water-filled and IP68 protection rating, maintenance-free.
- PE C-SJ1-25 centrifugal hydraulics in AISI 304 with integrated check valve, optimized for high pressure.
- Design performance of the set (with PS2-1800): 3.0 m³/h flow rate and 140 m maximum head.
- Reference system efficiencies (with PS2-1800): controller up to 98%, motor up to 92%, hydraulics ≈ 49%.
- Lorentz modular architecture: independent replacement of hydraulics, motor, or controller to reduce downtime.
- Designed for 4” wells with robust, quiet, and durable construction in clean water.
Advantages or Benefits
- Total flexibility: renew only the submersible part or design a custom high-pressure system with the most suitable controller.
- Minimal operating cost thanks to sealed brushless technology and high-strength stainless materials.
- Hydraulic safety due to the integrated check valve that prevents backflow and water hammer.
- Stable and efficient performance, maximizing liters pumped per available solar kWh.
- Simple installation in standard 4” boreholes, with compact dimensions and balanced weight.
Purpose or Applications
Especially suitable for deep wells, elevated tanks, medium/long-distance transfers, and pressurized irrigation (sprinkler/drip) on agricultural or livestock farms. Also suitable for domestic supply in isolated homes where pressure is prioritized over flow rate.
