Products FAQ`s

1. What are mechanical seals and why are they important?

Mechanical seals prevent leakage of liquids or gases between a rotating shaft and a stationary housing in equipment such as pumps, compressors, and mixers. They help maintain process efficiency, reduce maintenance costs, and protect equipment from contamination or fluid loss.

2. What type of applications are US-TB and US-TBR mechanical seals used for?

US-TB and US-TBR seals are designed for handling highly corrosive and chemically aggressive fluids. They are commonly used in chemical processing plants, fertilizer industries, acid handling systems, and pumps operating with reactive or corrosive media.

3. What is the difference between US-TB and US-TBR mechanical seals?

The US-TB seal features a replaceable rotary seal face, allowing easier maintenance and replacement. The US-TBR version uses an integral rotary face design, providing a compact structure suitable for certain corrosive applications.

4. What materials are used in US-TB / TBR mechanical seals?

These seals are manufactured using chemically resistant materials such as PTFE and GFT composite bellows, Silicon Carbide, Ceramic, Carbon, and corrosion-resistant metals like SS316 and Hastelloy C.

5. What operating conditions can these seals handle?

US-TB / TBR mechanical seals are designed for shaft sizes from 19 mm to 100 mm, temperatures from −45°C to 120°C, and speeds up to 2900 rpm, depending on application requirements.

6. Are these mechanical seals suitable for corrosive chemicals?

Yes. The seals are specifically designed for extremely corrosive environments. The use of PTFE based bellows and chemically inert materials makes them suitable for acids, salts, oxidizing agents, and reactive organic compounds.

7. Can these seals be customized for specific equipment?

Yes. Unique Seal Engineering Co. provides customization based on shaft size, operating pressure, temperature, and process fluid to ensure proper sealing performance for different industrial applications.
