The U.S. Seal PS-501 shaft seal is designed for compatible 5/8 inch shaft applications and uses Buna sealing material to restore the pump’s main rotating seal. In a quality rebuild, this is one of the parts that deserves careful attention, because the success of the repair often depends on how well the pump is sealed once it goes back into service.
This replacement is especially useful when the original seal has become brittle, started leaking, or reached the stage where reinstalling it would undermine the rest of the repair. Using the right shaft-size seal with the correct material helps keep the rebuild accurate, stable, and worth the investment.
The PS-501 is a dependable choice for service professionals and pump owners who want a solid, properly matched replacement part rather than a compromise.
