Third seal in five weeks

TS-3 raw milk transfer skid, P-101 mechanical seal · 10 min

P-101's carbon-on-ceramic seal has been replaced three times in five weeks. Each new seal weeps, then floods the drain slot, and LS-1 calls SEAL LEAK again within days. Stores wants to keep swapping seals; you want to know what keeps killing them, because a mechanical seal that dies this fast is being murdered by something OUTSIDE it. The old seal is on the bench. Read the failed part, then confirm the outside condition, and commit.
