How to use and precautions

1. Before using the pump, carefully check the pump and motor for damage. Check the fastener fastening.

2. Turn the pump to check for friction. Also check the concentricity of the pump shaft and the motor shaft. The deviation of the outer circle of the two coupling shafts does not exceed 0.5mm.

3. Connect the pipeline of the pump outlet. A bracket should be provided. It is not allowed to add the weight to the pump body.

4. The pump must be equipped with a fully automatic pump control cabinet without special circumstances. Do not connect the grid directly or use the knife switch to switch on the current. Make sure the pump is running normally.

5. Do not operate the pump for a long time under low lift (usually the head should not be lower than 60% of the rated head). It can be controlled within the recommended lift range. The waterproof pump burns the motor due to overload.

maintenance

1. The pump should be managed and used by a special person. Regularly check whether the circuit and pump of the pump are working properly.

2. After each use, especially for thicker and more viscous slurry, the pump should be placed in dehydration for a few minutes to prevent deposits in the pump. Ensure the pump is clean.

3. Under normal conditions, the pump should be filled or replaced with oil (10-30# oil) after every 300-500 hours of use. Keep the mechanical seal in good lubrication and improve the service life of the mechanical seal.

4. The sealing ring between the impeller and the pump body has a sealing function. If the sealing ring is damaged, it will directly affect the performance of the pump. If necessary, it should be replaced.
