Finish Thompson A101703-2 PVDF Barrier with Ceramic Shaft and Silicon Carbide Thrust Washer
The A101703-2 is the pvdf barrier with ceramic shaft and silicon carbide thrust washer used in Finish Thompson KC5.5, KC6, KC6H, KC7, KC8 and KC10 magnetic drive pumps. It seals the pumped fluid away from the drive magnet and carries both the ceramic shaft and the silicon carbide thrust washer the impeller runs against. It is built in PVDF with a ceramic shaft and silicon carbide thrust washer, which is what decides where it can safely be used.
Treat it as a service item rather than a permanent fitting. Look for cracking, a worn thrust face or scoring on the outside where the magnet passes, and renew it rather than trying to dress the face flat. 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: 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.
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.
