Mechanical Seals for high temperature Applications

What are the additional components required?

What can go wrong?

Several factors contribute to high temperatures in the seal chamber, which in turn leads to mechanical seal degradation.

At higher temperatures, elastomeric components in the mechanical seal may begin to deteriorate. For example, beyond 300° Fahrenheit (150° C) ethylene propylene components eventually degrade and leak.

When mechanical seals and seal support systems can no longer ensure pump reliability it’s time to select seals better suited for the job.

Mechanical Seals Materials Maximize performance And Reliability

Elastomerics

Those are formulated to tolerate specific hydrocarbons, temperatures, and flush fluids

Seal Faces

Carbon, stainless, ceramic, tungsten, and variants incorporating silicon, graphite, or nickel- engineered for resilience and compatibility with process fluids

Mechanical Seals Materials Maximize performance And Reliability

Low-expansion alloys

These are for metal seal components that minimize thermal expansion which jeopardize seal performance

The benefit of these choices is the ability to match mechanical seals to the specific needs of the process, maximizing seal performance and reliability.

Dual Mechanical seals for High- Temperature Environments

The mechanical seal requirements of high-temperature hydrocarbon processes are best met with dual/ between seal arrangements.

In contrast to a single mechanical seal arrangement, the two seal arrangement provides a more reliable means of preventing high-temperature hydrocarbons from leaking. Engineers have a number of dual seal design options to choose from, including:

Back-to-back   Face-to-face     Tandem
