Robert Pelikan delves into the actual pump selection process, how to read pump curves and charts, and how to select the right pump.
During the last few articles, we laid the groundwork for pump selection by showing how to determine the amount of water needed in terms of gallons per minute, and the pressure required in terms of psi or feet of head, to satisfy the requirements of a job. This month and next, we will go into the actual pump selection process, how to read pump curves and charts, and how to select the right pump.
Generally speaking, selecting a pump is a three-step process. First, determine the pumping requirements of the job as we did in the last few articles. Second, decide which brand and type of pump (jet pump or submersible) to use. Then go to the catalogs and select a pump.
