Frequently Asked Questions
The 150QJR is primarily designed for hot water mining, deep well water intake, agricultural and garden irrigation, high-rise water supply, and river water intake.
The motor uses a water-filled wet structure. You must ensure the motor cavity is completely filled with clean, non-corrosive water before installation to cool the motor and lubricate the bearings.
No, the 150QJR is suitable for clean water. It is strictly prohibited to use it for extracting sediment or turbid water, as this will cause premature damage to the pump.
To prevent the pump from sucking in mud or sediment, the bottom of the submersible pump should be no less than 3 meters from the bottom of the well.
We recommend taking the pump out for dismantling and maintenance after one year of operation, or after two years of diving time if operation was less frequent, to replace worn parts.
If the current exceeds 20% of the rated value, you should shut down the pump immediately to troubleshoot possible causes such as jamming, low voltage, or pipeline damage.
