Lorentz ECDRIVE 4000 HRE 4.0kW Solar Motor for pump

Product Description

The Lorentz ECDRIVE 4000 HRE 4.0kW Solar Motor is the professional option for driving helicoidal hydraulic bodies (HRE) in deep solar pumping projects. Its brushless architecture, water filling for cooling, and construction in AISI 304/316 stainless steel ensure reliability, long service life, and outstanding performance in 4" wells. With 92% efficiency and IP68 protection, it converts more photovoltaic energy into useful head, reducing the required panel power and the system's operating cost.

Main Features

• High rated power: 4.0 kW for high head and thrust applications with HRE bodies.
• Maximum efficiency 92%: more water per installed watt and lower thermal dissipation.
• Wide operating range: 900–3,300 rpm to match the daily variation of solar irradiation.
• Protection rating IP68 and water-filled motor for continuous submersible service.
• Premium construction: AISI 304/316, no internal electronics (external control), and maintenance-free design.
• 4" format: diameter 96 mm, height 265 mm, and weight 10 kg, ideal for narrow and deep wells.

Advantages or Benefits

• Reduced total cost of ownership: high efficiency and brushless technology lower the required PV power and maintenance.
• Superior reliability: by not incorporating electronics inside the motor, tolerance to humidity, temperature, and electrical transients is increased.
• Stable operation: the wide rpm range allows maintaining useful flow for more hours of the day, even with variable radiation.
• Durability: stainless materials and IP68 sealing for demanding environments and intensive use in professional solar pumping.
• Safety and simplicity: water cooling, silent operation, and spark-free, ideal for deep boreholes.

Purpose or Applications

Recommended for 4" wells with high water columns in deep solar pumping systems: potable water supply, drip and sprinkler irrigation, livestock, filling elevated tanks, and off-grid uses. In combination with an HRE helicoidal body, it prioritizes head with moderate flow rates, perfect for deep boreholes and long pipelines.

Technical Specifications

Compatibilities

Compatible with Lorentz HRE-type hydraulic bodies (helicoidal) of 4" and with Lorentz solar pump controllers. It can be integrated into PS2 systems (the controller is supplied with the complete system) or mounted in PU units (the controller is not included and must be purchased separately). For correct sizing, select the HRE body according to the required flow/head, size the PV array, and verify that the controller supports the electrical range and working currents of the assembly.

The Lorentz ECDRIVE 4000 HRE 4.0kW Solar Motor offers exceptional power, efficiency, and reliability to ensure safe water in deep solar pumping applications with minimal maintenance.
