Frequently Asked Questions
No, this pump is designed specifically for clean water. Pumping sediment or muddy water can cause premature wear and damage to the impellers and bearings.
The diving depth should not exceed 70 meters, and the pump should be placed at least 3 meters above the bottom of the well.
Ensure the motor cavity is completely filled with clean water before use and maintain a water flow between 0.7 and 1.2 times the rated flow.
The pump must be equipped with a distribution box providing short-circuit, overload, phase, undervoltage, and grounding protection.
We recommend lifting the pump for a full inspection and replacing wearing parts (impellers, seals) every year or every two years of immersion.
You must drain all water from the motor cavity to prevent ice damage and store the unit in an indoor area below 40°C.
