By using our design example, we
have determined the design conditions
for our well pump is 500 GPM at 269
feet TDH. This is a common design con-
dition for both pumps, vertical turbine
and submersible. Individual factors,
such as minor changes to friction loss
or lift, can be adjusted with the specific
pump.
Until then, keep them pumping!
