This is the third in a series on pump selection and pump performance curves and charts. In the last two articles, we discussed factors that should be considered when selecting a ground water pump, when to use a jet pump verses a submersible, how to convert from feet of head to psi, how to read performance curves, how performance curves are generated and how to estimate the cost of operation of a pump. This month, we will look at performance charts, another way to evaluate the performance characteristics of a ground water pump.
