Introduction: Mechanical seal failure is responsible for nearly 80% of centrifugal pump maintenance issues. At the heart of these failures lies the abnormal wear of the rotary and stationary rings. For engineers in the pulp, paper, and chemical industries—where equipment like Sulzer® or Andritz® pumps must run reliably—understanding these wear patterns is essential to preventing unscheduled downtime.
1. Non-Invasive Inspection: 3 Steps to Predict Failure

In the demanding environment of pulp and paper mills, pump reliability is dictated by the performance of its seal. For those operating Sulzer® APP, APT, or NPP series centrifugal pumps, finding a seal that can handle high-stock consistency without the premium OEM price tag is a constant challenge.FB

Understanding Single Cartridge Seal OverheatingAn overheating mechanical seal is a ticking time bomb for industrial pumps. When a single cartridge mechanical seal exceeds its designed operating temperature, it leads to premature face wear, elastomer degradation, and eventually, catastrophic leakage.
