How to Select the Right Seal Technology

Compression packing

In a recent podcast, sealing expert Chuck Tanner discussed the application factors and environmental compliance requirements needed to decide. Lori Ditoro, SEPCO

Regardless of a pump system’s age, if the process fluid changes—the pH, temperature, makeup (solids content/viscosity) or pressure—the seal technology may need to change. In new plants, these same parameters are used by plant and maintenance managers to decide what seal technology to specify.

In a February 2019 Rooted in Reliability podcast, SEPCO Director of Market Development Chuck Tanner joined host James Kovacevic, principal instructor with Eruditio to discuss:

  • The different sealing technologies
  • Why one technology is chosen instead of another
  • How end users can make the technology change if needed
Mechanical Seal

Compression packing is the most frequently used and oldest sealing technology available. However, packing must leak for optimal operation and to prevent premature failure. If environmental compliance requires that the fluid not leak, a mechanical seal or other technology must be used. If lubrication reliability is the application, a bearing isolator is the direction to take. When sealing slurries or powders, an air seal is often the ideal choice.
