A volute bolt may be a small part, but it helps determine whether the wet end feels secure and properly assembled, and this Balboa Volute Bolt is designed for compatible Ultimax, Ultra Flo, SuperFlo, and Ultima pump applications using a 1-5/8 inch length where the original hardware has been lost, corroded, or can no longer be trusted. In pump repairs, the right fastening hardware often has a bigger effect on confidence than its size suggests.

The compatibility across multiple related pump families gives this bolt practical service value, while the 1-5/8 inch size helps define the intended fastening relationship it was built to support. Correct hardware matters because a properly matched bolt helps maintain the original clamping and support relationship of the volute assembly.

Replacing the bolt is often one of the smartest focused repairs when the surrounding wet end parts remain serviceable. That helps keep the repair efficient while restoring a cleaner and more dependable feel to the assembly.

Installed in the proper pump setup, this bolt helps restore secure wet-end fastening and supports a better-finished, more confidence-inspiring repair overall.

  • 1-5/8 inch size supports intended fastening fit
  • Helps restore secure wet-end assembly support
