The 175QJB Deep Well Submersible Pump is a high-performance water extraction solution engineered for reliability in demanding environments. Utilizing advanced water-resistant motor windings, this series is specifically designed to withstand high-frequency shock, pulse peak voltage, and high-temperature aging. Its innovative frequency conversion design allows the motor to operate seamlessly between 1Hz and 50Hz, significantly reducing energy consumption while extending the overall service life of the equipment.
Built for versatility and durability, the 175QJB series features a water-filled wet structure for optimal cooling and lubrication. With a robust construction that includes a sand-prevention ring and high-quality submersible winding wire, these pumps ensure stable performance in applications ranging from agricultural irrigation to industrial water intake. Designed via computer CAD, the pump offers a streamlined structure that maximizes hydraulic efficiency and minimizes mechanical wear.

Frequently Asked Questions
The maximum immersion depth for this pump is 70 meters. We also recommend maintaining a minimum distance of 3 meters between the pump bottom and the well bottom to ensure optimal water intake.
No, the 175QJB is designed specifically for clean water. Pumping sediment, mud, or highly turbid water is strictly prohibited as it may cause premature wear to the bearings and impellers.
Frequency conversion allows the motor to operate smoothly between 1Hz and 50Hz. This adaptability reduces energy consumption and lowers mechanical stress, resulting in a longer service life.
Water temperature should be ≤ 20°C, pH value between 6.5-8.5, solid impurities ≤ 0.01%, chloride ions ≤ 400mg/L, and hydrogen sulfide ≤ 1.5mg/L.
No, the pump must be installed and operated strictly in a vertical position. Horizontal or inverted installation is not permitted and will lead to equipment failure.
To prevent freezing and damage to the motor chamber, all water inside the motor cavity must be drained before storing the pump in a location where temperatures may drop below the freezing point.
