The amount of water you can pump depends on several factors including your cylinder size, pumping speed, and well depth.

Water Output by Cylinder

CylinderOutput per StrokeTheoretical Max (60 strokes/min)
100CA4.5 oz~2.1 gallons/minute
125CA8.5 oz~4 gallons/minute
200CA20 oz~9.4 gallons/minute

These are theoretical maximums. Your actual output depends on your pumping pace, endurance, and well conditions. Most people sustain a comfortable pace rather than maximum speed.

Factors That Affect Output

Pumping Speed

  • Faster pumping = more water, but more tiring
  • Most people find a sustainable rhythm of 20-40 strokes/minute
  • Short bursts can achieve higher rates when needed

Water Depth

Deeper wells may require:

  • Slower, more deliberate strokes
  • More rest between pumping sessions
  • Smaller cylinder for easier operation

Priming Strokes

When starting to pump, initial strokes bring water up from depth before it flows from the spout:

Approximate DepthPriming Strokes Needed
50 feet10-15 strokes
100 feet20-30 strokes
150 feet30-45 strokes
200+ feet45-60 strokes

These are estimates. Your specific installation may vary.

Personal Factors

Your water output also depends on:

  • Physical fitness and endurance
  • Pumping technique
  • Rest periods taken
  • Time available for pumping

Realistic Daily Expectations

For planning purposes, consider what you can comfortably sustain:

  • 5-10 minutes of pumping: 5-20 gallons (depending on cylinder and pace)
  • Emergency water needs: Most families can pump 20-50 gallons per session
  • Filling storage tanks: Multiple sessions throughout the day

Maximizing Your Output

  1. Choose the right cylinder for your depth and strength
  2. Use proper technique - leverage body weight
  3. Pump into storage - fill tanks during good conditions
  4. Consider motor option for regular high-volume needs
