When You Need Pump Repair
Don't wait for complete failure. These symptoms indicate your pump needs professional repair:
- Excessive Vibration or Noise: Grinding, squealing, rattling, or abnormal sounds indicate bearing wear, misalignment, or internal damage.
- Reduced Flow or Pressure: Pump not delivering rated capacity. Performance degraded by 10% or more from baseline.
- Seal Leaks: Visible leaking from mechanical seal or packing gland area. Excessive seal water consumption.
- Bearing Failure: Hot bearings (>180°F above ambient), loose shaft play, bearing noise, grease contamination.
- Cavitation Damage: Loud popping/crackling sounds, vibration, erosion damage to impeller and casing.
- Impeller Wear: Clearances increased, efficiency decreased, uneven wear patterns, corrosion or erosion damage.
- Shaft Damage: Scored, bent, or worn shaft surfaces. Excessive runout. Coupling damage.
- Casing Corrosion: Internal corrosion, erosion, cracks, or material degradation affecting performance.
- High Power Consumption: Motor drawing excessive current for given operating conditions.
- Short Seal or Bearing Life: Repeated failures within months indicate underlying problems needing correction.
⚠️ Don't Ignore Warning Signs
Operating a damaged pump causes cascading failures. A $500 seal replacement ignored can turn into a $5,000 complete rebuild. Minor bearing noise today becomes a seized shaft tomorrow, destroying the impeller and damaging the casing.

Repair vs. Replace: Making the Right Decision
Not every pump should be repaired. We provide honest recommendations:
When Repair Makes Sense:
- Cost: Repair costs 30-50% of replacement cost
- Quality Pump: Well-built pump from reputable manufacturer
- Proper Size: Pump is correctly sized for application
- Parts Available: Repair parts readily available at reasonable cost
- Not Obsolete: Technology still current and efficient
- Quick Turnaround: Repair can be completed in reasonable timeframe
When Replacement May Be Better:
- Repair Cost High: Repair exceeds 60-70% of new pump cost
- Multiple Failures: Pump has failed repeatedly with expensive repairs
- Obsolete Technology: Newer pumps offer significant efficiency gains
- Wrong Size: Pump is significantly oversized or undersized
- Parts Unavailable: Manufacturer out of business, parts scarce or very expensive
- Severe Damage: Casing cracked beyond repair, major component failures
✓ Honest Recommendations
We'll tell you honestly if repair doesn't make economic sense. We can source new pumps if replacement is the better option. Our goal is to solve your problem cost-effectively, not sell unnecessary repairs.
