Product Description:
The YTB121 and YTB122 are balanced structure pump mechanical seals designed for various operating conditions. They can handle pressures from 0 to 1.0 MPa, temperatures ranging from -40 to 220℃, and speeds of less than 3000 r/min. These seals are suitable for media such as petroleum, chemicals, LPG, weak acids, alkalis, salts, and media with a few particles.

Design and Structure:
These seals feature a single face mechanical seal driven by a lug, characterized by a simple structure and short axial dimension. They allow for unlimited rotation direction and have a short lug. The assembled thrust ring prevents spring drop, facilitating installation. The assistant seal options include PTFE coated rubber or rubber o-ring. The YTB121 uses a multi-spring structure for even load distribution, while the YTB122 employs a wave plate spring structure for stability and reliability, making them suitable for higher pressure applications.

Competitiveness:
The products offer high performance at a competitive price, with prompt delivery and excellent service. They boast a longer service life and low energy consumption, with customization available to meet customer requirements. 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. The company has also been awarded several utility patents for seal research and design.

Product Application:
The YTB121 series is commonly used in various pumps and has been widely applied in the petroleum, chemical, and coal chemical industries, including ethylene, oil refining, and fertilizer sectors.
