Specifications
Product Description
The Lorentz PU1800 C-SJ30-1 Submersible Solar Pump is a professional pump unit designed to move large volumes of water with minimal head. It combines the PE C-SJ30-1 centrifugal hydraulic body in AISI 304 stainless steel with a high-efficiency ECDRIVE submersible motor, achieving up to 49 m³/h flow rate with 10 m of lift. This version is a PU without controller, intended for integration with Lorentz controllers from the same platform (e.g., PS2-1800), which provide MPPT, protections, and automation with probes and float switches.
Main Features
- Maximum flow rate of 49 m³/h and maximum head of 10 m, ideal for 6” wells.
- PE C-SJ30-1 centrifugal hydraulics in AISI 304 with integrated check valve.
- ECDRIVE 1200/1800-C motor, brushless, IP68, water-lubricated; nominal power approx. 1.7 kW.
- High overall efficiency; quiet operation and minimal maintenance.
- Lorentz modular architecture for fast service and spare parts availability.
- PU (Pump Unit) version: does not include controller; prepared for solar systems with external MPPT control.
Advantages or Benefits
- High flow rate for rapid filling of tanks, reservoirs, and transfers using solar energy.
- Robust stainless steel construction ensures long service life in clean water.
- Integrated check valve protects the water column and prevents backflow.
- Simple installation and maintenance thanks to modular design and availability of original spare parts.
- Scalability: when paired with the appropriate controller, allows automation with probes, float switches, and dry-run protection.
Purpose or Applications
Recommended for agriculture and livestock, transfers between tanks, reservoir refilling, and gravity or low-pressure sprinkler irrigation. Suitable as a replacement pump unit in existing systems that already have a compatible controller, or as a base for a new system to which a photovoltaic controller will be added.

Compatibilities
This unit does not include a controller. It is compatible with Lorentz controllers from its family, such as PS2-1800 (adds MPPT, protections, inputs for well probe and float switches). When paired with PS2-1800, the PV generator must be sized for an aggregate Vmp > 102 V, total Voc ≤ 200 V DC, and the Isc within the controller’s admissible range. Uses Lorentz accessories and spare parts from the C-SJ series and ECDRIVE motors.
The Lorentz PU1800 C-SJ30-1 offers an optimal balance between extreme flow, reliability, and efficiency, enabling the creation of high-performance submersible solar pump systems to move large volumes of water with photovoltaic energy.
