Specifications
Product Description
The Lorentz PU4000 C-SJ3-32 Submersible Solar Pump is a professional submersible unit for 4” wells that combines a 4.0 kW ECDRIVE motor with the PE C-SJ3-32 centrifugal hydraulic body in stainless steel. Designed to provide high pressure and stable flow in demanding solar installations, this version does not include a controller, making it suitable for integration with an existing Lorentz PS2-4000 controller or for configuring a custom system. Its modular architecture reduces installation times and facilitates maintenance, offering performance, robustness, and efficiency with very low operating costs.
Main Features
- Unit (Pump Unit) with brushless ECDRIVE 4000-C motor (4.0 kW), water-filled, IP68 sealed, and maintenance-free.
- PE C-SJ3-32 centrifugal hydraulic in AISI 304 with integrated check valve to protect the discharge line.
- Design performance of the assembly: up to 4.2 m³/h and 220 m head when used with the appropriate controller.
- High system efficiency: controller (when using PS2-4000) up to 98%, motor up to 92%, hydraulics up to 52%.
- Compact format for 4” wells, silent operation, and high reliability for intensive work.
Advantages or Benefits
- Total flexibility: integrate this PU with the Lorentz PS2-4000 controller you already have or the one that best suits the PV field.
- High pressure for elevated tanks, pressurized irrigation, or long lines with significant losses.
- Virtually zero maintenance thanks to the brushless motor and stainless steel hydraulics.
- Modularity: allows independent replacement of motor, hydraulics, or controller, reducing downtime and costs.
- Energy efficiency that maximizes the water pumped per available solar kWh.
Purpose or Applications
Especially suitable for deep wells, elevated tanks, sprinkler/drip irrigation with pressure, long-distance transfers, and light agricultural or industrial applications that require high water column with photovoltaic energy.

Compatibilities
Direct compatibility with Lorentz PS2-4000 Controller and with PE C-SJ3-32 hydraulics (included). Supports dry well sensors, level switches, remote start/stop, and standard 4” discharge accessories. For the PV field, configure strings that respect the controller’s window (generator Isc ≤ controller limit and Vmp within the operating range).
The Lorentz PU4000 C-SJ3-32 Submersible Solar Pump is the ideal modular solution when you need to renew only the submersible part or design a custom high-pressure system: power, reliability, and efficiency to deliver water where other systems cannot reach.
