Specifications
Product Description
The Lorentz PU1800 C-SJ42-1 Submersible Solar Pump is a modular pumping unit for 6” wells that combines the brushless ECDrive motor and the centrifugal hydraulics PE C-SJ42-1. It delivers up to 53 m³/h with 8 m of head, ideal when the goal is to move large volumes with low lift. Its stainless steel construction and integrated non-return valve ensure reliability and long service life. This PU (Pump Unit) version is the pump only; it requires a compatible external controller. Controller not included.
Main Features
- Centrifugal hydraulics C-SJ42-1 (1 stage) optimized for 53 m³/h and 8 m.
- ECDrive 1200-C / 1800-C brushless motor, water-filled, IP68, high efficiency.
- Construction in AISI 304 stainless steel and technical polymers for intensive service.
- Integrated non-return valve (NRV): prevents backflow and water hammer.
- Modular architecture: independent replacement of hydraulics or motor.
Advantages or Benefits
- High flow rate with very low head: perfect for rapid tank filling, gravity irrigation, and transfers.
- Low operating cost: brushless motor and water cooling with minimal maintenance.
- Premium materials that increase durability and reduce downtime.
- Flexibility: the installer selects the controller according to the available PV array.
Purpose or Applications
Agriculture, livestock, ponds, and light industrial uses where water volume is prioritized over pressure, in off-grid or self-consumption solar installations.
