Lorentz PE C-SJ8-15 Hydraulic Body for submersible solar pump

Product Description

The Lorentz PE C-SJ8-15 Hydraulic Body is the original centrifugal head for submersible solar pumps designed to combine high pressure with constant flow in 4" wells. Manufactured from AISI 304 stainless steel and featuring an integrated check valve, it delivers up to 13 m³/h and 80 m head, ensuring hydraulic reliability, water column protection, and sustained performance in professional irrigation and transfer applications. Its architecture, optimized for use with Lorentz ECDRIVE motors, ensures easy integration, minimal maintenance, and spare parts availability.

Main Features

• Maximum flow: 13 m³/h; maximum head: 80 m.
• Centrifugal hydraulics with integrated check valve.
• Reference maximum hydraulic efficiency: ≈ 68 %.
• Robust construction in AISI 304 stainless steel.
• For 4" wells; water temperature ≤ 50 °C.
• Head weight: ≈ 10 kg (specification value).

Advantages or Benefits

• Higher water column with stable flow for moderate/high pressure irrigation.
• Corrosion resistance and long service life in demanding environments.
• Check valve prevents backflow and protects the installation.
• Original Lorentz spare part: perfect fit and guaranteed performance.
• Direct integration with ECDRIVE motors and PU/PS2 systems of the same family.

Purpose or Applications

Recommended for pressurized agricultural irrigation, supply to elevated tanks, transfers with elevation difference, and supplies requiring higher pressure without sacrificing reliability. Operates in off-grid or hybrid solar systems.

Technical Specifications

Compatibilities

Compatible with Lorentz ECDRIVE 4000-C motors and with PU4000 C-SJ8-15 units and systems with PS2-4000 C-SJ8-15 controller. Use as a direct replacement in assemblies of the same series and diameter.

The Lorentz PE C-SJ8-15 Hydraulic Body provides high pressure, durability, and easy integration for professional solar pumping projects in 4" wells.
