Finish Thompson M100109-1 Polypropylene Housing Cover
Finish Thompson supplies the M100109-1 as the polypropylene housing cover for GP11 sealed centrifugal pumps. It closes the impeller housing and forms the face that sets the running clearance in front of the impeller. It is built in polypropylene, which is what decides where it can safely be used.
Most pumps see this part replaced well before the pump itself needs attention. Wear or chemical attack on the inside face opens that clearance up, and the pump quietly falls off its curve without any other symptom. Confirm the material and size against your pump before ordering, as the same position is offered in several variants across this range.

Frequently Asked Questions
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.
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.
