Sta-Rite 111P0500 Mechanical Seal Rotating Face
This is the 111P0500 mechanical seal rotating face. A leaking shaft seal shows up as water dripping from underneath the pump, near where the motor meets the pump body, while the pump is running or just after it shuts off.
Shaft seals wear from normal use, from a pump that has been run dry even briefly, and from grit in the water that gets between the two faces. Handle the sealing faces by their edges only during installation, since a fingerprint or a speck of grit on the polished face can cause a leak from day one.

Frequently Asked Questions
Q: Can I touch the sealing face when installing this?
Avoid it. Handle the mechanical seal rotating face by its outer edge only; a fingerprint or a speck of dust on the polished sealing face can cause a leak as soon as the pump is started.
Q: What causes a shaft seal to fail early?
Running the pump dry even briefly, sand or grit in the water, and simple age are the most common causes. A seal that fails within weeks of installation usually points to a face that got contaminated during assembly.
Q: Should I replace the impeller when I replace this seal?
Not always, but inspect it while the pump is open, since the two parts often wear under the same conditions.
Q: Will this fit a different pump in the same series?
Match the exact part number on the old seal rather than assuming similar-looking pumps share the same size.
