Specifying Mechanical Shaft Seals for Silverson In-Line Mixers
Silverson's latest animation explains why some applications require single mechanical shaft seals, and why others require double mechanical seals on In-Line mixers.

For many applications, a single mechanical shaft seal is all that is required to prevent liquid from leaking out of the mixing chamber. But if you are mixing materials that are abrasive or sticky in nature this can cause problems where a single mechanical seal is being used. Abrasive materials cause the seal faces to wear, and sticky substances can solidify between the seal faces when the mixer is switched off; this can cause the seal rings to seize and break when the mixer is restarted. To avoid this a double mechanical seal would be recommended. The new video discusses this and other aspects of seal specification.
