Finish Thompson A101008-1 Polypropylene Barrier with Ceramic Shaft
The A101008-1 is the polypropylene barrier with ceramic shaft used in Finish Thompson KC11 magnetic drive pumps. It is the sealed cup that separates the pumped fluid from the drive magnet, and it carries the ceramic shaft the impeller turns on. It is built in polypropylene with a ceramic shaft and thrust ring, which is what decides where it can safely be used.
Treat it as a service item rather than a permanent fitting. A barrier is replaced when it is cracked, worn through on the inside face, or scored by a decoupled magnet, and any of those let chemical reach the drive end. When ordering, match the part to the pump as it was actually built rather than to the catalog model alone, since material and size options were specified at the time of purchase.

Frequently Asked Questions
Q: Is this the genuine manufacturer part?
Yes. It is the factory component built to the original specification rather than a pattern copy.
Q: Should anything else be replaced at the same time?
Whatever the teardown exposes. Elastomers and bushings are inexpensive and are best renewed while the pump is already apart.
Q: What causes most premature failures on this part?
Running the pump outside what it was specified for, whether that is temperature, viscosity, dry running or an incompatible chemical.
Q: Does fitting this affect the pump warranty?
Using the factory part keeps the pump to its original specification, which is what any warranty position depends on.
