What to do if the motor protection is tripping on my PVR Water Pump?
- K
  Kylie AcostaAug 8, 2025
  If your PVR Water Pump's motor protection is tripping, it could be due to several reasons. It may be caused by pump seizure and jam, requiring a pump overhaul. Another possible cause is a broken vane, which means you should replace the vanes. Inefficient exhaust filters can also cause this problem, so replace them. Finally, high temperature due to polluted oil can cause the motor protection to trip, so you should change the oil.

  Evan ClaytonAug 12, 2025
  If you notice a drop in performance in your PVR Water Pump, several factors could be the cause. The inlet filters might be dirty, in which case you should clean or replace them. A blocked oil cooler can also lead to reduced performance, so clean or replace it. Lack of lubrication can also be the cause, so fill the pump with oil to the correct level, or change the oil and oil filter. Lastly, a worn coupling element can lead to performance issues, so replace it if necessary.

  If your PVR Water Pump is producing discharge oil mist, it could be due to a high operating temperature caused by a high ambient temperature. To resolve this, decrease the room temperature by allowing better air exchange. Also, check that the inlet valve is tight.

Damaged vanes can also cause unusual noises, so replace them. Damaged contact surfaces may be the issue, requiring a pump overhaul at our workshop. Finally, worn shaft oil seal rings can cause noise, so replace the oil seal rings.
