Specifications
Product Description
The Lorentz PU4000 HRE-05HHL Submersible Solar Pump is a pump unit (Pump Unit) designed for high-pressure applications in 4” wells. It combines the 4.0 kW, sealed, IP68 ECDRIVE 4000-HRE motor with the PE HRE-05HHL helical head, made of AISI 304/316 stainless steel and equipped with a non-return valve. This version is supplied without controller, allowing integration with an existing PS2-4000 or the design of a custom system according to the available photovoltaic array. Together with the appropriate controller, it achieves up to 0.92 m³/h and 450 m, providing a robust, efficient, and virtually maintenance-free solution for projects that prioritize head over flow rate.
Main Features
- Submersible unit with ECDRIVE 4000-HRE brushless, water-filled motor, IP68, and no electronics in the motor.
- PE HRE-05HHL helical head in AISI 304/316 with integrated non-return valve as standard.
- Performance of the set (with PS2-4000): 0.92 m³/h and 450 m maximum head.
- Lorentz modular architecture for independent component replacement and fast service.
- Silent operation and maintenance-free thanks to sealed brushless technology.
Advantages or Benefits
- Total flexibility: renew only the submersible part or create a custom high-pressure system with PS2-4000.
- Minimal operating cost due to the combination of brushless motor and stainless steel materials.
- Hydraulic safety thanks to the integrated check valve, which prevents backflow and water hammer.
- Stable performance with high heads even in variable irradiance scenarios.
Purpose or Applications
Deep wells, very high tanks, long-distance transfers, pressurized irrigation on steep terrain, and light industrial projects where extreme pressure is required with solar energy.
