Frequently Asked Questions
The maximum diving depth for this pump is 70 meters, provided it is installed vertically and the bottom of the pump remains at least 3 meters above the bottom of the well.
This pump is designed for clean water. It is strictly prohibited to use it for pumping sediment or muddy water, as this can lead to premature damage to the internal components.
The motor uses a water-filled wet structure. Filling the cavity with clean, non-corrosive water is essential for cooling the motor and lubricating the rubber bearings during operation.
Violent vibration may indicate improper installation or that the pump is rubbing against the well wall. You should shut down the machine immediately and check the pump's position and stability.
If the storage location falls below freezing, you must drain the water from the motor cavity to prevent ice expansion from damaging the motor structure.
Common applications include deep well water intake, high-rise building water supply, agricultural and garden irrigation, and river water intake for industrial use.
