Finish Thompson A101761-1 PVDF Impeller 6-1/8 Inch
The A101761-1 is the pvdf impeller 6-1/8 inch used in Finish Thompson GP22 and GP32 pumps with bellows or multispring seals. It is the six and one eighth inch impeller that generates the head and flow in the sealed GP series pump. 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. Impellers lose output gradually as the vane tips and shroud wear, and a pump that no longer reaches its duty point with everything else in good order usually needs one. 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: 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.
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.
