Finish Thompson A101981-7 Polypropylene Impeller Housing with Thrust Ring
This is the factory polypropylene impeller housing with thrust ring for Finish Thompson KC7, KC8 and KC10 magnetic drive pumps with NPT connections. It forms the pumping chamber with NPT suction and discharge ports and carries the thrust ring the impeller bears against. It is built in polypropylene, which is what decides where it can safely be used.
It is one of the parts worth renewing on schedule instead of waiting for a fault. A housing with a grooved thrust face or a worn bore no longer holds the running clearance, and the pump loses head long before anything looks obviously broken. Check the pump build before ordering, because these pumps are offered in more than one material and size combination and the alternatives look similar on the shelf.

Frequently Asked Questions
Q: How should the pump be flushed before service?
With a fluid known to be compatible, so the parts can be handled safely and the old chemical is not carried into the rebuild.
Q: Can the pump be run briefly without this part?
No. Every component in the wet end carries a load or seals a joint, and running incomplete risks far costlier damage.
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.
