mechanical seal（YTB132）

Product catalog summary

Product Description
YTB132 metal bellows mechanical seal is designed for use in roots blowers and compressors. It operates under pressures from -0.1 to 2.5 MPa and temperatures ranging from -75 to 400℃. The seal supports linear speeds of less than 30 m/s and is suitable for high viscosity media, including those with major solid particles and corrosive media up to 150℃. Constructed from stainless steel, carbon, metal, and graphite, it features a single face, bellows structure, and can rotate in any direction. The design includes a flexible graphite gasket or PTFE pad as an auxiliary seal ring, ensuring stable and reliable performance.

Design and Structure
The seal has a simple structure with an even load on the end face. The bellows is stationary, with a floating fixed position to match the rotary part's end face. It is modular, facilitating on-site installation and maintenance, and uses wear-resistant materials for friction pairs.

Competitiveness
The YTB132 seal offers high performance at a competitive price, with prompt delivery and excellent service. It boasts a longer service life, low energy consumption, and can be customized. With over 20 years of design and manufacturing experience, the company is a long-term vendor for Sinopec and Petro China and holds ISO9001, ISO14001, and QHSAS18001 certifications, along with several utility patents.

Product Application
The YTB132 series is ideal for high viscosity media and is widely used in pumps, compressors, roots blowers, and similar equipment.
