All centrifugal pumps have a shaft seal installed. The purpose of these shaft seals is to stop the water or liquid that is pumped from leaking along the shaft.

Some pump seals are installed a little differently in some swimming pool and spa pumps; however, the principle purpose of the seal is the same. And that is to stop leaks.
