Lorentz ECDRIVE 600 HRE 0.7kW Solar Motor for pump

Product Description

The Lorentz ECDRIVE 600 HRE 0.7kW Solar Motor is a direct current submersible motor designed to drive helicoidal hydraulic bodies (HRE) with maximum reliability in solar pumping systems. Its brushless architecture, water filling, and AISI 304/316 stainless steel construction ensure maintenance-free, quiet, and efficient operation, even in narrow 4" wells. With IP68 and a maximum immersion of 150 m, it offers stable performance in demanding environments, optimizing flow with less installed photovoltaic power.

Main Features

• 0.70 kW nominal power for head and thrust applications with HRE helicoidal bodies.
• Maximum efficiency of 92%: more water per watt of solar panel.
• Wide operating range: 900–3,300 rpm to adapt to available irradiation.
• IP68 and water filling for continuous submersible service and reliable cooling.
• Construction in AISI 304/316, corrosion-resistant; no internal electronics (external control).
• Compact format: Ø96 mm, height 203 mm, and weight 6.7 kg for 4" wells.

Advantages or Benefits

• Minimal maintenance: brushless technology and water-filled motor reduce wear and downtime.
• Energy efficiency: high motor efficiency reduces the required PV power and system cost.
• Reliability: with no electronics inside the motor, robustness against humidity and temperature is increased.
• Versatility: the rpm range allows following the solar curve and maintaining useful flow for more hours per day.
• Durability: stainless materials and IP68 sealing designed for intensive use in professional solar pumping.

Purpose or Applications

Suitable for 4" wells in drinking water supply projects, drip or sprinkler irrigation, livestock, filling elevated tanks, and off-grid applications. In combination with an HRE helicoidal body, it provides good manometric head with moderate flow rates, ideal for deep boreholes and high water columns.

Technical Specifications

Compatibilities

Compatible with Lorentz HRE-type hydraulic bodies (helicoidal) of 4" and with Lorentz solar pump controllers. It can be integrated into both PS2 systems (the controller is supplied with the system) and PU units (the controller is not included and must be purchased separately). For any project, size the photovoltaic array according to the required flow and manometric head, and verify that the selected controller supports the electrical range and currents of the assembly.

The Lorentz ECDRIVE 600 HRE 0.7kW Solar Motor is the professional option to achieve more water, with greater reliability and less maintenance, in deep well solar pumping.
