Continuous leakage from a mechanical seal on a pump indicates the seal should be

• A. Replaced
• B. Repaired
• C. Tightened
• D. Cleaned

Answer: (A)

Continuous leakage from a mechanical seal signals that the sealing surfaces are worn or damaged and can no longer seal the pump shaft. Mechanical seals rely on intact faces, O-rings, and springs to keep fluid contained; once leakage occurs persistently, those components have degraded beyond reliable repair. Tightening won’t fix the underlying wear and can even cause more damage, and cleaning doesn’t restore worn sealing surfaces. In this situation, replacing the entire mechanical seal assembly is the reliable, safe course to restore proper containment and prevent further leakage.
