Pumping air occasionally won't immediately damage your Simple Pump motor, but sustained dry running can cause problems. Understanding the risks helps you protect your investment.
Short-Term Air Pumping
Occasional Air Pockets
- Risk: Low
- Effect: Motor runs but no water delivered
- Duration: Brief periods are normal
- Happens during priming or low water
What Happens
When the cylinder is above water:
- Piston moves but pumps air
- No water resistance
- Motor runs faster than normal
- Minimal lubrication from water
Sustained Dry Running Risks
Seal Wear
- Water lubricates cylinder seals
- Dry operation increases friction
- Extended dry running accelerates seal wear
- May require earlier seal replacement
Heat Buildup
- Water helps cool the cylinder
- Dry operation generates more heat
- Excessive heat can damage components
- More concern in deep installations
Motor Stress
- No-load conditions less efficient
- Rapid cycling not ideal
- Extended dry running wastes power
Protection Strategies
Float Switch Installation
Recommended for motorized systems:
- Detects low water level
- Shuts off motor automatically
- Prevents sustained dry running
- Simple installation
Timer Control
For scheduled pumping:
- Limits pump runtime
- Prevents continuous operation
- Allows well recovery between cycles
- Reduces risk of pumping dry
Manual Monitoring
For backup use:
- Listen for change in pump sound
- Watch for air in output
- Stop motor if running dry
- Restart when water recovers
Low Yield Well Considerations
If you have a low yield well:
Prevention
- Place cylinder deeper in water column
- Allow well recovery between pumping
- Use timer to limit cycles
- Monitor water level
Signs of Low Yield
- Well runs dry during pumping
- Long recovery time between sessions
- Seasonal water level changes
- Known low yield from driller
Warranty Implications
What's Covered
- Manufacturing defects
- Normal wear and tear
- Proper use per instructions
What May Affect Coverage
- Sustained operation without water
- Failure to use recommended protections
- Ignoring low water conditions
- Repeated dry running damage
Best Practices
For All Motor Installations
- Use float switch - Automatic protection
- Don't run continuously - Allow rest periods
- Monitor operation - Watch for issues
- Maintain seals - Replace when worn
For Low Yield Wells
- Timer control - Limit runtime
- Storage tank - Accumulate slowly
- Deep cylinder placement - More water above
- Seasonal awareness - Adjust for conditions
If You've Run Dry
After Brief Dry Running
- Usually no damage
- Resume normal operation
- Monitor for issues
After Extended Dry Running
- Inspect for problems
- Check seal condition
- Listen for unusual sounds
- Contact support if concerned
