What to do if my China Nanfang Pump SZ Water Pump trips out?

  Micheal MarshallAug 16, 2025
  If your China Nanfang Pump Water Pump trips out or the start load is too high, several factors could be at play. It could be due to a blown fuse (replace the fuse), an issue with the contact of the overload device (check the starter), a loose power supply cable or a defect in the power supply itself (check the cables and power supply). In more serious cases, the motor windings might be defective (replace the motor) or pump parts could be blocked (check the pump). Also, ensure you've closed the discharge valve before starting; if not, close it and restart.

Why China Nanfang Pump Water Pump pumps no water?

  Samuel RuizAug 19, 2025
  If your China Nanfang Pump Water Pump isn't pumping water, several issues could be the cause. First, check if the discharge valve is closed and open it. Also, the pump might not be sucking water, or the liquid level could be too low, so adjust the pump's location. Ensure you've filled enough liquid and vented any air from it. A blocked suction could also be to blame, so clean the suction. Finally, the pump itself might be damaged, requiring repair or replacement.
