Hand Pump Sizing Calculator
Find the right pump for your well.
Enter your well's details below. We'll calculate your Total Dynamic Head (TDH)
and color-code every pump in our database based on how much effort it would take to pump water
at your depth. Green is easy,
Yellow is marginal,
Red is not recommended for your scenario.
Feet from ground surface down to the water in your well when it's at rest.
Feet of additional elevation gain from wellhead to where the water is delivered. Use 0 if pumping into a bucket at the wellhead.
Target pressure if pumping into a pressure tank (40–60 PSI is typical). Use 0 if not pressurizing.
Total Dynamic Head (TDH)
The total "lift" your pump must overcome — water level + rise + (PSI × 2.31)
— ft
Easy (under 30 lbs/stroke)
