Lorentz PE C-SJ3-9 Hydraulic Body for Submersible Solar Pump
Modelo: 14-000095 PE C-SJ3-9, Rp 1 1/4"- Sku: LOREREP010
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PE C-SJ3-9 Hydraulic Body is the original centrifugal head for 4” submersible solar pumps. Manufactured from AISI 304 stainless steel and featuring an integrated check valve, it provides an excellent balance between flow rate and head for residential, agricultural, and livestock applications. As an official replacement or as a base for new configurations, this hydraulic unit offers efficient, quiet, and highly robust hydraulics for intensive use in clean water. Depending on the motor/controller it is paired with, it can reach up to 4.1 m³/h and 50 m, or operate in lower power versions with 3.3 m³/h and 35 m, maintaining stable curves and benchmark hydraulic efficiency.
Main Features
- Centrifugal series C-SJ3-9, specific for 4” wells and medium flow rates.
- Construction in AISI 304 stainless steel for high durability.
- Integrated check valve: prevents column return and water hammer.
- Maximum reference hydraulic efficiency: 53% (with compatible motor).
- Lorentz modular architecture: quick assembly/replacement and easy maintenance.
- Fully compatible with ECDRIVE motors and PU/PS2 units of the same family.
Advantages or Benefits
- Reduces downtime and maintenance costs as an original replacement.
- Greater safety in the discharge line thanks to its integrated check valve.
- Premium materials ensure long service life in clean water.
- Balanced curve for tanks, transfers, and gravity or low-pressure irrigation.
Purpose or Applications
Perfect for maintenance and upgrading of submersible solar pumps in off-grid homes, farms, livestock, and small irrigation installations. Suitable for 4” wells, tank filling, and transfers with medium-length lines.
