Specifications
Product Description
The Lorentz PU4000 C-SJ5-25 Submersible Solar Pump is a pump unit designed to provide high pressure with stable flow in 4" boreholes. It integrates the centrifugal hydraulic body PE C-SJ5-25, made of AISI 304 stainless steel with a check valve, and a submersible motor ECDRIVE 4000-C of 4.0 kW, IP68, and water-lubricated. With performance up to 7.0 m³/h and 140 m head, it is ideal for medium/high-pressure irrigation, elevated tanks, and transfers with significant elevation difference. This version is PU (does not include controller), prepared to work with Lorentz controllers that provide MPPT, protections, and automation with probes and float switches.
Main Features
- Hydraulic performance: 7.0 m³/h flow and 140 m head.
- Centrifugal hydraulics PE C-SJ5-25 in AISI 304 with check valve; efficiency ≈ 54 %.
- Motor ECDRIVE 4000-C brushless, IP68, no electronics in the motor; nominal power ~4.0 kW.
- Lorentz modular architecture: easy installation and service with original spare parts.
- Silent operation and low maintenance in continuous operation with photovoltaic energy.
- Recommended well diameter: 4"; clean water up to 50 °C.
Advantages or Benefits
- High pressure for sprinkler irrigation, pivots, or very high tanks without the need for generators.
- Long service life thanks to stainless materials and brushless motor.
- Integrated check valve that prevents backflow and protects the water column.
- Scalable: by adding a Lorentz controller, you get MPPT, protections, and level-based automation.
- Perfect as a replacement pump unit in existing systems or as a base for a new system.
Purpose or Applications
Suitable for medium/high-pressure agricultural irrigation, transfers with large elevation differences, supply to elevated tanks, and internal networks in farms. Optimal for off-grid or hybrid solar systems where pressure is required without compromising reliability.

Compatibilities
This unit does not include a controller. It is compatible with Lorentz controllers from its platform, such as PS2-4000 (adds MPPT, protections, and level control). When paired 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-SJ5-25 provides high pressure, efficiency, and industrial reliability to build high-performance submersible solar pump systems.
