Lorentz PE C-SJ3-18 Hydraulic Body for Submersible Solar Pump
Modelo: 14-000100 PE C-SJ3-18, Rp 1 1/4"- Sku: LOREREP011
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PE C-SJ3-18 Hydraulic Body is the original centrifugal head for 4" submersible solar pumps, designed to provide stable flow and medium-high pressure in photovoltaic installations. 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.
Main Features
- C-SJ3-18 centrifugal series for 4" wells, balanced flow/head performance.
- Manufactured in AISI 304 stainless steel, corrosion-resistant in clean water.
- Integrated non-return valve: prevents column return and water hammer.
- Maximum reference hydraulic efficiency: up to 54% with compatible motor.
- Lorentz modular architecture that facilitates installation and maintenance.
- Hydraulic curve suitable for tanks, gravity irrigation, and medium lines.
Advantages or Benefits
- Maintains original performance as an official replacement compatible with Lorentz motors.
- Reduces downtime due to failures thanks to premium materials and robust design.
- Greater hydraulic safety due to its integrated non-return valve.
- Stable performance over a wide operating range, optimizing water per solar kWh.
Purpose or Applications
Suitable 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.
