Shaft Seal for High-Pressure Cement Slurry: High lifespan, low friction, excellent sealing performance, compact design, and easy installation, use, and maintenance. Its special sealing lip and optimized thickness design provide good sealing even in harsh media such as cement slurry. When used for sealing mud-like media, we recommend grease lubrication between two (or more) seals.

When you encounter any questions or emergencies during the use of your products, you can contact Ruichen at any time. We provide a 7 x 24 hour technical consultation hotline for handling urgent technical problems.
In the event of a seal leak, abnormal wear or any performance failure, our technical support team will initiate the response process immediately with a phone call or email. We can provide you with preliminary judgment and solutions through remote video diagnosis, image analysis and other methods. For complex problems, we promise to give a preliminary analysis report within 48 hours, and if necessary, send engineers to the site to provide technical support, and jointly investigate the problem with you until the problem is completely solved.

Note: 1. For shaft diameters ≤ 30mm, an open groove design is recommended.
2. When used for rotary seals, a surface hardness of HRC ≥ 58 for the rotating shaft is recommended.
3. For pressures greater than 30MPa, an H8/8 fit is recommended for the extrusion gap.
