SEE REPLACEMENT PART: OBSOLETE

Shaft seal kits are one of the most important parts in a pump rebuild because they protect the boundary between the motor and the wet end, and this Balboa pump shaft seal kit is designed for compatible Gemini, H-Pump, Magna, and ITT Marlow LD Series applications. When the original seal starts to wear, the pump can quickly lose the reliability that makes it worth keeping in service.

Replacing the shaft seal is often a smart repair when the pump motor still has life left but the wet-end side is beginning to show the signs of age. A good seal kit helps restore that critical sealing point and gives the overall rebuild a much stronger foundation.

Because this kit is meant for multiple compatible pump families, it offers practical flexibility while still keeping the repair correctly matched to the intended equipment. That matters because sealing components need to fit and perform accurately if the finished repair is going to feel dependable.

Installed in the proper pump setup, this kit helps restore a cleaner seal between the motor and water-side components and supports a more complete and confidence-inspiring pump rebuild.
