Common Failures & Troubleshooting

Despite their robustness, gear pumps may experience failures due to wear, contamination, or improper maintenance. Common issues include:

6.1 Low Pressure or Flow

• Causes: Worn gears, internal leakage, clogged filters, or air ingress.

• Solutions: Inspect and replace damaged gears, check for leaks, clean/replace filters, and bleed air from the system.

6.2 Overheating

• Causes: Excessive load, low fluid levels, or degraded oil.

• Solutions: Ensure proper oil viscosity, maintain correct fluid levels, and avoid overloading.

6.3 Excessive Noise & Vibration

• Causes: Cavitation, misalignment, or bearing wear.

• Solutions: Check suction lines for restrictions, realign pump shafts, and replace worn bearings.

6.4 Fluid Leakage

• Causes: Damaged shaft seals or worn housing.

• Solutions: Replace seals and inspect the pump casing for cracks.
