Improving Sealing Solutions at a Chemical Manufacturing Plant [Case Study]

Sepco Case Study Improving Sealing Solutions at a Chemical Manufacturing Plant

Improving Sealing Solutions at a Chemical Manufacturing Plant [Case Study]



A Texas-based Manufacturing Plant in operation since 1990, producing specialty chemicals. Over the years, the plant faced recurring issues with its sealing solutions, leading to frequent downtimes, maintenance costs, and product losses.

The Challenge:

The plant’s primary challenge was the frequent failure of seals in their main reactors. These failures resulted in:

  • Unscheduled downtimes, averaging 15 hours per month.
  • Product losses amounting to approximately $20,000 per month.
  • Maintenance and replacement costs of around $10,000 per month.
  • Potential safety risks to the plant’s personnel and the environment.

The Solution:

After a thorough audit by SEPCO, it was determined that the existing seals were not suitable for the high-temperature and corrosive environment of the reactors. SEPCO recommended:

  • Upgrading to a high-performance, corrosion-resistant seal designed for high-temperature applications.
  • Implementing a regular maintenance and inspection schedule to detect wear and tear before it led to seal failure.
  • Training the plant’s maintenance staff on best practices for seal installation and care.

The Implementation:

Over a scheduled maintenance weekend, the old seals were replaced with the recommended high-performance seals. The maintenance team underwent a two-day training program, and a bi-monthly inspection schedule was set up.

The Results:

Within the first three months after the upgrade:

  • Unscheduled downtimes reduced to zero.
  • Product losses decreased by 95%.
  • Maintenance and replacement costs dropped by 80%.

Over a year, the plant saved:

  • 180 hours in downtime, translating to increased production time.
  • $240,000 in product losses.
  • $96,000 in maintenance and replacement costs.

The total annual savings amounted to $336,000, not counting the intangible benefits of improved safety and increased staff confidence.


The case of this Manufacturing Plant underscores the importance of using the right sealing solutions tailored to specific operational conditions. By investing in high-quality seals and proper training, plants can realize significant savings, improve safety, and boost operational efficiency.
