Finish Thompson A101981-9 PVDF Impeller Housing with Thrust Ring
The A101981-9 is the pvdf impeller housing with thrust ring used in Finish Thompson KC7, KC8 and KC10 magnetic drive pumps with NPT connections. It is the pumping chamber and port body, supplied with the thrust ring the impeller runs against. It is built in PVDF, which is what decides where it can safely be used.
Treat it as a service item rather than a permanent fitting. Renew it when the thrust face is grooved or the bore has been worn by an impeller running off center, since both open up the clearance that sets pump output. 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.
