Sometimes there is not enough net positive suction head available (NPSHA) for your pump, causing it to cavitate.

One option to stop cavitation is to install a booster pump between the suction of your pump and the source of the fluid you are pumping. This reduces the amount of friction loss in the piping and in most cases solves the net positive suction head available (NPSHA) problem.

Booster pumps are frequently located between condensate pumps and the boiler feed pump in steam power applications.

Another option is to use an inducer that attaches to your present pump’s impeller.
