In industrial fluid handling, chronic mechanical seal failure is a high-stakes challenge for plant reliability teams. When a newly installed seal suffers heavy leakage within days—or even hours—of service, it is common to attribute the breakdown to "substandard seal quality" or "improper maintenance installation."
However, seasoned reliability engineers recognize that many catastrophic seal failures are actually caused by two stealthy hydraulic phenomena occurring deep within the pump chamber: Dry Running and Cavitation. This technical guide explains exactly how these two operational hazards destroy seal components and outlines the heavy-duty engineering defenses required to secure long-term reliability.
