The flow system has the ability to test the pumps as a single unit or as a two pumps connected in series or parallel. The results show that connecting the pumps in parallel gave a better resistance to cavitation than series connection and single pump operation. For the series installation, consider a pipe that runs from pump A to pump B. If 20 gpm is flowing out of pump A, into pump B, what will come out of pump B? If it's not 20 gpm, where does the extra come from or go to? For the parallel operation, assume the two pumps have a common suction and discharge.
