The Berkeley L03649 balance ring is a cast iron replacement component for compatible B4ERBMS pump assemblies. It has a 4-3/4-inch inside-diameter fit.
The ring is a separate pump component, not the wearing ring or a complete seal assembly. Match L03649 to the pump bill-of-material number and the existing component before ordering.
Replacing the specified balance ring allows the existing pump to be serviced at the component level. Inspect the adjoining gasket and mating surfaces during disassembly, and select any additional replacement parts separately.

| 4-3/4-inch ID fit | Provides a dimensional check alongside the part-number match. |
