For certain applications, industries may require non-standard profiles of rotary shaft seals. In such cases, Techné's engineering office offers its expertise and experience to develop new dedicated rotary shaft seal profiles for specific customer applications.
The engineering office's support may involve validation or recommendations, all the way to the complete development of a project, including product definition, drawings, numerical simulations, and prototype production.
As an initial approach, Techné's engineering office invites customers to fill out a design form. All necessary information, such as rotational speed, service temperature, contacting fluids, housing and shaft materials, will be analysed. A profile specific to the customer's requirements will be designed and proposed.

The client provides details about the application and operating environment: pressure, speed, temperature, etc.
Selection of a mixture with optimized abrasion resistance
Definition of the shape of the rotary shaft seal, appropriate surface roughness, dimensions, and tolerances
Creation of the design plan
Prototype tool manufacturing
Design and manufacturing of a test bench
Endurance testing of the rotary shaft seal for 3 months in different fluids with regular checks
Presentation of test results to the client for final approval
Materials
Depending on the operating temperatures and chemical environment, Techné offers several materials for rotary shaft seals on request:
Metal reinforcement: steel or stainless steel (different grades upon request)
Elastomeric part:
