Technical Knowledge

In the demanding environment of chemical processing, the reliability of fluid handling equipment hinges on one critical component: the mechanical seal. A single seal failure can lead to costly downtime, safety hazards, and environmental compliance issues.
While seal design is vital, material science is often the deciding factor between a leak-free operation and catastrophic failure. This guide provides a technical framework for matching seal faces and elastomers to aggressive chemical media, with a specific focus on the complexities of sulfuric acid (H2​SO4).

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 Pulp & Paper and Mining industries, pump mechanical seal failures account for over 60% of unscheduled downtime. If you are tired of replacing seals every 3 months on your slurry pumps, you are not alone.While many engineers blame "bad seal quality," the reality is often found in the operating

If you are asking “Why is my centrifugal pump mechanical seal leaking?”, you aren't alone. Mechanical seal leakage is the #1 cause of pump downtime globally. Whether you see a steady drip or a sudden spray, understanding the causes of mechanical seal failure is essential to prevent recurring costs a

The Invisible Enemy of Mechanical SealsYou’ve invested in a high-quality single cartridge mechanical seal, followed the installation manual to the letter, and ensured your API flushing plan is operational. Yet, within weeks—or even days—the seal begins to leak.When you strip the pump, the faces are
