SEALING SYSTEM ANALYSIS


Sealing systems that have been properly designed and tested will prove to be extremely reliable and provide long service life. To optimize a seal design, it is recommended to involve deVries engineering in the original design development. For maximum sealing system efficiency and performance the seal and its adjacent components should be considered as a single unit in the design failure mode effects and analysis (FMEA) phase. It is our aim to help you minimize the number of components, simplify assembly, and reduce the need for costly manufacturing tolerances and procedures to create the best system results.

On occasions, sealing systems do fail and this section is designed to help you isolate the root cause of any failure. When an assembly leaks, the natural response is that the seal is bad. A thorough investigation is needed to correctly identify the root cause. It is necessary to review potential variations in system function and environmental conditions. In addition, shaft condition and function, bore condition and any wear or physical variation in the seal must also be examined.

This section is divided into three parts: a list of common reasons sealing systems fail and variables that lead to those failures, a preliminary guide to failure analysis, and a copy of the deVries International system failure analysis report. It is the goal of deVries International to provide immediate and thorough technical assistance in helping you evaluate any seal related failure. For best results, technical support is available by contacting deVries Internationalís headquarters at 949-252-1212 or a regional sales office near you at the first sign of a problem.
