What To Pay Attention To When Using Submersible Pumps?
Once the submersible pump fails, do not disassemble it by yourself.
During the non-use period, the submersible pump should be lifted away from the water source in time.

Proper use of submersible pumps can achieve maximum efficiency

Technical guidance on the use and maintenance of agricultural submersible pumps
How to Maintain a Submersible Pump?
Check the wearing parts
Replace lubricating oil
Disassemble the pump casing to prevent rust
Ensure sealing
Dry the motor
Ensure bearing lubrication

Check the bearings

Which is better, the screw pump or the impeller pump, which is more durable ?
Both impeller pumps and screw pumps have their own advantages.
Working efficiency, the impeller water pump is generally higher than the screw water pump;
The working pressure of the screw water pump is generally higher than that of the impeller water pump;
The working flow rate of the impeller pump is generally higher than that of the screw pump.
Work reliability, screw pumps are generally better than impeller pumps.

Water pump engine failure and repair.
The hot antifreeze has a smell. Use a mirror and a light to see if there is water leakage at the vent of the water pump.
The bearing is damaged and the pump shaft is seized.
The impeller is corroded, the coolant is red and rusty.
Whether the coolant circulates normally.
The water pump is overheated.

Causes of large current when the submersible pump is running.
Motor guide bearing wear, water pump rubber bearing wear, seal ring wear
Thrust bearing wear, submersible pump impeller and lower cover wear
The flow rate of the submersible pump is too large or too small
The shaft of the submersible pump is bent and the bearing is not concentric

Precautions and Solutions
The water pump does not work.
Insufficient water output from the water pump
The pump beeps for a few seconds and then stops
