Many factors, whether small or large, have an impact on the run time of a mechanical seal. We collect all the existing parameters, analyze and interpret them together with our customers. In the following steps, we will discuss changes on the system, whether they are on the design part of the seal, the support system or the whole arrangement. For example, occurring heat, which is directed on the seal faces and elastomers, causes failures of the seal. We will offer solutions (such as API plans) which will generate a cooling effect on the critical parts to make the mechanical seal run longer and safer. Another way could be changing the elastomers, which are designed to resist hot surroundings like this.

With 15 years of experience in the field of mechanical sealing, we have become a specialist in the modification of modern sealing systems.
