Specifications
Product Description
The Lorentz PU1800 C-SJ8-7 Submersible Solar Pump is a pump unit designed to offer an excellent balance between flow rate and pressure in 4" boreholes. It combines the centrifugal hydraulic body PE C-SJ8-7 in AISI 304 stainless steel with a high-efficiency ECDRIVE submersible motor. It reaches up to 13 m³/h and 40 m head, making it ideal for sprinkler/low-medium pressure irrigation, elevated tanks, and transfers with elevation difference. This version is PU (does not include controller), intended for integration with Lorentz controllers that provide MPPT, protections, and automation with probes and float switches.
Main Features
- Hydraulic performance: 13 m³/h flow rate and 40 m head for 4" wells.
- Hydraulics PE C-SJ8-7 with integrated check valve and efficiency ≈ 63 %.
- ECDRIVE 1200/1800-C motor, brushless, IP68, water-lubricated; nominal power ≈ 1.7 kW.
- Construction in AISI 304 stainless steel for all parts in contact with water.
- Lorentz modular architecture: fast assembly and maintenance, original spare parts available.
- Silent operation and low maintenance (no brushes or electronics in the motor).
Advantages or Benefits
- Excellent flow–pressure balance for irrigation at multiple outlets and tanks at elevated levels.
- Long service life thanks to stainless materials and sealed motor design.
- Integrated check valve that protects the installation and prevents backflow.
- Scalable: by adding a Lorentz controller, you obtain MPPT, protections, and level control.
- Ideal as a replacement pump unit in existing systems or as a base for a new system.
Purpose or Applications
Suitable for agriculture and livestock, internal networks on farms, transfers with elevation difference, tank filling, and sprinkler/low-medium pressure irrigation in off-grid or hybrid solar installations.

Compatibilities
This unit does not include a controller. It is compatible with Lorentz controllers from the PS2-1800 family (they add MPPT, protections, inputs for well probe and float switches). When pairing with PS2-1800, size the PV generator for aggregate Vmp > 102 V, total Voc ≤ 200 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 PU1800 C-SJ8-7 provides pressure and flow with industrial reliability, enabling high-performance submersible solar pump systems in 4" wells.
