Appendix A: Performance Curves
Example: A long Bottom-Loading AP-2 with a 1/2-inch discharge hose and 70 psi supply
pressure positioned 100 feet below ground and submerged 6 inches below the fluid will
produce about .77 gallons per minute (GPM).
The same pump submerged 10 feet below the fluid produces 1.0 GPM.
Note:
These flow rates are only applicable for the designated well head conditions.
Any additional resistance from out-of-well equipment (e.g. surface hoses,
valves, etc.) will affect the values shown on these curves.
With the previous information, obtain the flow rate by using the following steps:
• On the horizontal scale, find the depth in the well at which the pump will be located.
• Trace that depth upwards to the line for the air inlet pressure you selected.
• Travel horizontally over to the vertical scale and read the flow rate.
