- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU4000 C-SJ8-15 Submersible Solar Pump is a pump unit designed to provide high pressure with stable flow in 4" wells. It combines the centrifugal hydraulic body PE C-SJ8-15 in AISI 304 stainless steel and a 4.0 kW ECDRIVE 4000-C submersible motor, achieving up to 13 m³/h with 80 m head. This version is PU, meaning controller not included; it is intended to be integrated with Lorentz controllers that add MPPT, protections, and automation with probes and float switches.
Main Features
- Performance: 13 m³/h flow and 80 m head for 4" wells.
- Centrifugal hydraulics PE C-SJ8-15 with integrated check valve (≈68% efficiency).
- ECDRIVE 4000-C brushless motor, IP68, water-lubricated; nominal power ~4.0 kW.
- Robust construction in AISI 304 stainless steel for parts in contact with water.
- Lorentz modular architecture for quick assembly and maintenance, with original spare parts.
- Silent operation and minimal maintenance.
Advantages or Benefits
- Excellent pressure for sprinkler irrigation and elevated tanks with solar energy.
- Long service life: stainless materials and brushless motor.
- Check valve that protects the water column and prevents backflow.
- Scalable: by adding a Lorentz controller, you obtain MPPT, protections, and level control.
- Simple integration as a replacement pump unit in existing systems.
Purpose or Applications
Suitable for agricultural irrigation at medium/high pressure, supply to elevated tanks, transfers with elevation difference, and internal networks on farms. Suitable for off-grid or hybrid solar installations where pressure is required without compromising flow.

Compatibilities
This unit does not include a controller. It is compatible with Lorentz controllers from its platform, such as PS2-4000 (MPPT, protections, inputs for well probe and float switches). When pairing with PS2-4000, size the PV generator for aggregate Vmp > 238 V, total Voc ≤ 375 V DC, and an Isc within the controller's admissible range. Use Lorentz accessories and spare parts from the C-SJ series and ECDRIVE motors.
The Lorentz PU4000 C-SJ8-15 offers high pressure, efficiency, and reliability for building professional submersible solar pump systems in 4" wells.
