The 125QJR Deep Well Submersible Pump is a high-performance industrial solution specifically engineered for underground hot water mining and challenging fluid environments. Capable of handling water temperatures up to 100°C, this pump is distinguished by its exceptional heat resistance, corrosion resistance, and anti-aging properties, ensuring reliable operation where standard pumps fail.
Designed for versatility and power, the 125QJR utilizes a powerful three-phase AC 380V motor with a sophisticated water-filled cooling and lubrication system. Whether used for agricultural irrigation, high-rise water supply, or industrial water intake, its CAD-optimized structure provides a perfect balance of energy efficiency and structural stability in the harshest subterranean conditions.

Frequently Asked Questions
It is designed for deep well water intake, high-rise water supply, mountain water supply, agricultural and garden irrigation, river water intake, and domestic water needs, specifically in hot water mining environments.
Ensure the motor cavity is completely filled with clean, non-corrosive water before use and that the pump is fully immersed in water to prevent dry running.
The 125QJR series is specifically engineered to handle underground hot water with temperatures reaching up to 100°C.
It is recommended to dismantle and repair the pump every operating year, or every two years of total submersible time, to replace worn parts like impellers and sealing rings.
Use waterproof cables, ensure reliable grounding, and install a distribution box with short-circuit, overload, and phase protection.
Immediately shut down the equipment. Check for jamming, verify if the pump is running against the well wall, or inspect for motor insulation failure.
