Lorentz ECDRIVE 4000 C 4.0kW Solar Motor for pump

Product Description

The Lorentz ECDRIVE 4000 C 4.0kW Solar Motor is a submersible direct current motor designed for professional solar pumping applications that demand maximum robustness and performance in 4" wells. Its maintenance-free brushless architecture, water filling for effective cooling, and AISI 304/316 stainless steel construction make it a reliable and durable solution for agricultural, livestock, and supply projects. With maximum efficiency of 92% and IP68 protection, it converts more solar energy into useful flow, reducing system costs and ensuring a continuous water supply even under demanding conditions.

Main Features

• Nominal power: 4.0 kW for high flow and head demands.
• Max efficiency 92%: more water per watt, less need for PV surface area.
• Speed range: 900–3,300 rpm to match daily irradiation variability.
• Protection rating: IP68, suitable for continuous submersible operation.
• Premium construction: AISI 304/316, no electronics in the motor, and water filling.
• 4" format: diameter 96 mm, height 263 mm, and weight 10 kg, ideal for narrow wells.

Advantages or Benefits

• Reduced total cost of ownership thanks to high efficiency and brushless technology that minimizes maintenance.
• Superior reliability: with no internal electronics, the motor better withstands humidity, temperature, and transients.
• Stable operation for more hours per day, adjusting rpm to the available solar resource.
• Long service life due to stainless materials and IP68 sealing, suitable for environments with water containing dissolved solids.
• Simple integration into new or existing solar pumping systems, with external Lorentz control.

Purpose or Applications

Recommended for 4" wells in large water supply demands, sprinkler or pivot irrigation, rapid tank filling, intensive livestock, farms, agricultural operations, and off-grid industrial uses. In combination with centrifugal bodies, it provides high flow rates at medium heads, making it a versatile choice when performance and service continuity are prioritized.

Technical Specifications

Compatibilities

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

The Lorentz ECDRIVE 4000 C 4.0kW Solar Motor delivers power, efficiency, and reliability for professional solar pumping projects that require more flow with minimal maintenance.
