You’ve dug a shallow well and installed a centrifugal pump to help extract water. While the pump is pulling up a generous number of gallons per minute, you’re finding that it’s producing very little pound-force per square inch. Should you install a second pump to help produce more PSI?
The answer to that question depends on whether or not you want to spend extra on the electricity it will take to keep both pumps running. If money is not at issue, then you have two more challenges to deal with: (1) deciding whether you want a booster or submersible pump and (2) making sure that the two pumps will work in harmony with each other.
While a booster pump will use less electricity than a submersible, the latter is definitely more efficient than a centrifugal pump. Regardless of the type you choose, you will need to make sure that the flow range of the secondary, matches that of your primary.
You’ll need to deal with wiring issues, too, in addition to how you’ll start both pumps. An irrigation controller connected to a relay that’s in turn connected to the pumps might do the trick. But if the pumps exceed the capacity of a single relay, you might need to install a second one.
It’s also a good idea to think about how you’ll handle problems such as pump malfunction. If one suddenly gives out, then the drag created by the malfunctioning pump might quickly destroy the other. This is not as big of an issue if you’re there to handle it. But if you’re away when it happens, you could be in some trouble.
