1. Low Flow or No Flow Issues:

• Possible Causes: Clogged impeller, air leaks in suction line, or worn-out pump components.
• Troubleshooting Tips:
  • Inspect the impeller for debris or blockages and clean if necessary.
  • Check suction line connections for air leaks and tighten fittings.
  • Examine pump components such as seals and bearings for wear and replace if needed.

2. Pump Cavitation:

• Possible Causes: Insufficient NPSH (Net Positive Suction Head), improper pump sizing, or high fluid velocity.
• Troubleshooting Tips:
  • Increase NPSH by lowering fluid temperature or reducing suction lift.
  • Verify pump sizing and ensure it matches system requirements.
  • Adjust impeller speed or install a larger pump to reduce fluid velocity.

3. Excessive Vibration:

• Possible Causes: Misalignment, worn bearings, or resonance with piping.
• Troubleshooting Tips:
  • Check and realign motor and pump shafts if misaligned.
  • Inspect bearings for wear and replace if necessary.
  • Install vibration dampeners or supports to reduce resonance.

4. Leakage Issues:

• Possible Causes: Damaged seals, worn gaskets, or loose connections.
• Troubleshooting Tips:
  • Replace damaged seals or gaskets promptly.
  • Tighten loose connections and fittings.
  • Consider upgrading to high-quality sealing materials for improved durability.

5. Motor Overheating:

• Possible Causes: Overloading, inadequate cooling, or high ambient temperatures.
• Troubleshooting Tips:
  • Reduce pump load or install a larger motor if consistently overloaded.
  • Ensure proper ventilation and cooling around the motor.
  • Shield the motor from direct sunlight or relocate to a cooler area if possible.

6. Abrasive Wear:

• Possible Causes: Pumping abrasive fluids or particles present in the fluid.
• Troubleshooting Tips:
  • Use abrasion-resistant materials for pump components, such as hardened alloys or ceramics.
  • Install a strainer or filter to remove solid particles from the fluid.
  • Regularly inspect and replace worn parts to prevent further damage.
