Safety Warning
- •Pump disassembly required - electrical and mechanical hazards
- •Worn impellers can fail suddenly causing damage
- •Improper installation affects pump performance and safety
- •Impeller balance critical for vibration-free operation
Impeller Wear Assessment
Flow Rate Measurement
Compare actual flow to pump specifications
⚠️ Warning: Reduced flow indicates impeller wear or damage
Visual Impeller Inspection
Remove pump housing to examine impeller condition
⚠️ Warning: Worn vanes reduce pumping efficiency significantly
Clearance Check
Measure impeller-to-volute clearance gaps
⚠️ Warning: Excessive clearance allows flow recirculation
Vane Condition Assessment
Check vane thickness, length, and edge condition
⚠️ Warning: Cavitation damage appears as pitted or eroded vanes
Balance and Runout Test
Check impeller balance and shaft straightness
⚠️ Warning: Unbalanced impeller causes vibration and bearing wear
Types of Impeller Wear
Mechanical Wear
- • Abrasive Wear: Sand and debris erosion
- • Cavitation Damage: Bubble collapse pitting
- • Corrosion: Chemical attack on metal
- • Fatigue Cracking: Repeated stress cycles
- • Impact Damage: Large debris strikes
Performance Impact
- • Reduced Flow: Up to 30% loss possible
- • Higher Energy Use: Pump works harder
- • Poor Circulation: Dead spots develop
- • Increased Vibration: Unbalanced operation
- • Premature Failure: Other components stressed
Signs of Impeller Wear
- • Gradual decrease in flow rate over time
- • Higher electricity bills for same operation
- • Longer filtration cycles needed
- • Pool takes longer to clear after shocking
- • Increased pump noise or vibration
