Lorentz PE C-SJ42-1 Hydraulic Body for submersible solar pump

Product Description

The Lorentz PE C-SJ42-1 Hydraulic Body is the original centrifugal “pump end” for 6” submersible systems, optimized to move large volumes of water with very low head. With a performance of up to 53 m³/h and 8 m of lift, high-quality stainless steel materials, and an integrated non-return valve, this replacement restores your solar pump’s factory flow while maintaining the reliability and efficiency characteristic of Lorentz.

Main Features

• Centrifugal hydraulics (1 stage) for 53 m³/h flow and 8 m maximum head.
• Constructed from AISI 304 stainless steel for maximum corrosion resistance.
• Integrated non-return valve (NRV) that protects the water column and prevents water hammer.
• Maximum hydraulic efficiency approximately ≈67 %, reducing the required PV power.
• Format for 6” wells with robust design and easy maintenance.

Advantages or Benefits

• Restores the original flow without replacing the motor or controller, minimizing downtime.
• Cost savings compared to replacing the complete pump, with compatibility and guaranteed quality.
• Superior durability due to its stainless steel construction and industrial design.
• Direct installation thanks to the integrated NRV; simpler and safer installation.

Purpose or Applications

Especially suitable for gravity irrigation, rapid tank filling, water transfer, and recirculation in ponds or reservoirs where high flow with low lift is the priority.

Technical Specifications

Compatibilities

Compatible with Lorentz ECDrive 1200-C / 1800-C motors and with PS2-1800 C-SJ42-1 (with controller) and PU1800 C-SJ42-1 (without controller) pumps. Typical accessories: level sensors, dry well protection, DC type II protections, submersible cable, and piping/hose sized for the flow rate.

Lorentz PE C-SJ42-1 Hydraulic Body is the professional option to restore extreme flow with reliability and long service life in large-volume, low-head solar pumping systems.
