Frequently Asked Questions
It allows the motor to operate stably between 1HZ and 50HZ, enabling precise control over water flow and significantly reducing energy consumption while prolonging the equipment's life.
No, this pump is designed specifically for clean water. It is strictly prohibited to discharge sediment or mud, as this can cause premature wear and damage to the internal components.
The pump must be installed strictly in a vertical position. It cannot be used horizontally or tilted, as this would compromise the bearing lubrication and motor stability.
The water temperature should be ≤ 20°C, solid impurities ≤ 0.01%, pH value between 6.5-8.5, and chloride ion content ≤ 400mg/L.
Dry running is strictly prohibited. The pump relies on water for lubrication and cooling; running without water will cause immediate and severe damage to the rubber bearings and motor.
Typically, the pump should be dismantled for maintenance after one year of operation, or after two years of diving time if it has been operated for less than a year.
