Came off a running pump (edge pump <2 hours week, 4 year old unit).
Pump it came from had worn bearings is reason for it's dissembly.
Case (not shown) is weathered, and one section has a chip that the case lid conceals and is still water proof as it should be.
I have other parts unlisted, message me if you need something else I might have.
Guaranteed working
