The plastic self-priming pump will also have problems in use. Now there is no manufacturer on the market that can guarantee that its own pump will not have problems in use. The reasons for the leakage of the plastic self-priming pump in use and the solutions were sorted out and shared to everyone.

The shaft seal is burnt. (Replace the shaft seal with a new one, and check the pipeline to find out the cause of burning)

The fixing ring is broken, the shaft seal shield and the rotating ring are broken, and the expansion ring is broken. (Look for hard or sharp impurities, and replace the broken part)

The impeller lock cap is not locked or sealed well. (Replace and lock the impeller lock cap and seal ring)

A part is corroded. (Replace it with a better one, or the material is suitable for the potion)

During installation, the shaft center height is too high, or the expansion ring is not pressed to the bottom. (Dismantle and readjust the shaft center height. Ensure that the expansion ring is pressed to the bottom during installation)

The motor spindle is separated from the shaft center, and the impeller rises. (Re fix the shaft center to ensure that the socket head cap screws are locked)

If you pay more attention when using the plastic self-priming pump, the service life will be longer.
