Different operating requirements require different designs. The company's product development and application technology are bundled into one unit to provide the best possible support for customers and to offer the best individual solution - whether to adapt an existing product or to develop a new design. Based on many years of experience and expertise, GOETZE® has developed a robust analysis tool for the design of face seals.
This tool makes it possible to evaluate new sealing geometries by simulation, or to find solutions for existing problems with customer applications. The virtual design is then validated by a series of laboratory and test bench trials, which include preload, spring characteristics, temperature and wear parameters. Special requirement tests, such as long-term and mud box tests, supplement validation.
This version is a further development of the standard type 76.95. The advantage of using this sealing system is the prevention of axial displacement caused by dirt-encrusted elastomer parts. Furthermore, it prevents the metal and elastomer parts from spinning at higher break-away and friction torque.
To fulfill these requirements, a retaining lip is located on the back of the seal rings to support the trapezoid ring against axial displacement. The seal rings are also provided with pockets, which allow the elastomer parts to grip into the retaining lip in a positive-locking way.
All other features correspond to the seal type 76.95.
Mechanical face seal type 76.95H modifies 75.95 seals for the prevention of axial displacement caused by dirt encrusted elastomer parts. Furthermore, it prevents the metal and elastomer parts from spinning at higher break-away and friction torque.
