Lorentz ECDRIVE 1800 HRE 1.7kW Solar Motor for pump

Product Description

The Lorentz ECDRIVE 1800 HRE 1.7kW Solar Motor is a direct current submersible motor specifically designed to drive helicoidal hydraulic bodies (HRE) in high-performance solar pumping projects. It combines brushless maintenance-free technology, water filling for effective cooling, and AISI 304/316 stainless steel construction, ensuring durability and reliability under demanding conditions. With a maximum efficiency of 92% and IP68 protection rating, it converts more solar energy into useful head, optimizing investment in panels and control.

Main Features

• High nominal power: 1.7 kW for installations requiring high thrust with HRE bodies.
• Maximum motor efficiency: 92%, more water per watt of installed panel.
• Wide operating range: 900–3,300 rpm to adapt to daily irradiation variability.
• IP68 protection and water-filled motor suitable for continuous submersible service.
• Premium materials: AISI 304/316 corrosion-resistant; no internal electronics (external control).
• Format for 4" wells: Ø96 mm, height 203 mm, and weight 6.7 kg for narrow boreholes.

Advantages or Benefits

• Reduced total cost due to lower maintenance: brushless technology and water-based lubrication/cooling.
• Superior reliability by eliminating electronics inside the motor, less sensitive to humidity and temperature.
• Stable performance with more useful hours per day thanks to the wide rpm range.
• Long service life due to its stainless steel construction and IP68 sealing, ideal for intensive use.
• Better hydraulic adaptation to high heads with moderate flow rates typical of helicoidal bodies.

Purpose or Applications

Recommended for 4" wells in deep solar pumping systems intended for potable water, drip or sprinkler irrigation, livestock, filling elevated tanks, and off-grid uses. In combination with an HRE body, it is the ideal solution when head is prioritized over flow rate.

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 included in the system) or 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 currents of the assembly.

The Lorentz ECDRIVE 1800 HRE 1.7kW Solar Motor offers the perfect combination of efficiency, robustness, and minimal maintenance to ensure reliable water supply in deep solar pumping applications.
