Lorentz PE C-SJ1-25 Hydraulic Body for submersible solar pump
Modelo: 14-000080 PE C-SJ1-25, Rp 1 1/4"- Sku: LOREREP009
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PE C-SJ1-25 Hydraulic Body is the original centrifugal head for 4” submersible solar pumps, designed to operate at high pressure with moderate flow rates in deep wells. Manufactured from AISI 304 stainless steel and equipped with an integrated non-return valve, it provides reliability, durability, and optimized hydraulic performance. In configurations with the appropriate Lorentz ECDRIVE motor and PS2 controller, it can achieve up to 3.0 m³/h flow rate and 140 m head, making it the ideal option for replacement, preventive maintenance, or for building a new PU/PS2 unit based on the C-SJ1-25 series.
Main Features
- Centrifugal hydraulics C-SJ1-25 series for 4” wells, optimized for high water column.
- Construction in AISI 304 stainless steel, high resistance to corrosion in clean water.
- Integrated non-return valve to prevent backflow and water hammer.
- Reference performance: up to 3.0 m³/h and 140 m with the appropriate motor/controller.
- Typical maximum hydraulic efficiency: ≈ 49 %, stable and quiet curve.
- Lorentz modular architecture for quick replacement and service.
Advantages or Benefits
- Official replacement that maintains original performance and full compatibility with Lorentz motors.
- Greater hydraulic safety thanks to the integrated check valve.
- Premium materials that reduce downtime and long-term maintenance costs.
- Efficient performance that maximizes water pumped per available solar kWh.
Purpose or Applications
Designed for high-pressure solar pumping: deep wells, elevated tanks, pipelines with significant elevation difference, or irrigation requiring high head. Also suitable for medium/long-distance transfers in photovoltaic installations where pressure is prioritized over flow rate.
