In the demanding environment of pulp and paper processing, the efficiency of your screening operation is only as reliable as its weakest component. For operators utilizing the KADANT® ULTRA-V™ (UV) Vertical Screen, maintaining the integrity of the cartridge drive assembly is critical.
At FBU, we specialize in high-precision sealing solutions. Our 2550 Series Single Mechanical Seal is specifically engineered to be a 100% compatible, high-performance replacement for KADANT® UV series pressure screens, ensuring your operations stay leak-free and efficient.
Why the KADANT® UV Series Demands Superior Sealing
The KADANT® Ultra-V™ screen is renowned for its innovative bottom-fed design, which optimizes the movement of contaminants and protects the rotor mechanism. However, the robust cartridge drive that powers these rotors requires a mechanical seal that can handle:
Varying consistencies of pulp.
High-velocity rotations.
Pressure fluctuations within the modular body.
The FBU 2550 Series is designed to meet these rigid standards of durability and maintenance ease, matching the "long lifetime" promise of the Ultra-V™ system.
Introducing the FBU 2550 Series: The Perfect Fit
The FBU 2550 Series is a stationary pusher seal with a balanced design, engineered specifically for the UV series. Whether you are running a UV200 or a massive UV600, our seals provide a seamless fit without the need for equipment modification.
Technical Features & Advantages
Stationary Pusher Seal, Balanced Design: Reduces face loading and heat generation, extending the life of the seal faces even under high-pressure conditions.
Multi-Spring Structure: Features a stable spring compensation mechanism that remains unaffected by shaft misalignment or high-speed vibrations.
Simplified Installation: A streamlined structure means faster maintenance turnarounds, reducing downtime for your screening plant.
Versatile Material Options: Available in 316SS, Duplex Steel, Titanium, and other specialized alloys to suit corrosive or abrasive media.
Full Compatibility Range
Our 2550 Series covers the entire spectrum of KADANT® UV models and shaft diameters, including:
Models: UV200, UV300, UV400, UV500, UV600.
Shaft Diameters: 54mm, 80mm, 100mm, 140mm, and more.

FAQ
1. Is the FBU 2550 Series a direct drop-in replacement for the KADANT® UV original seal?
Yes. The 2550 Series is specifically designed to match the dimensions and performance requirements of the KADANT® UV series (UV200-UV600). It can be installed directly into the existing seal chamber without modifications.
2. Can the 2550 Series handle high-consistency pulp?
The 2550 Series is ideally suited for water and low-consistency pulp. For applications involving extremely high-consistency stock or heavy recycled fibers, we recommend consulting with our technical team to select the optimal face materials (such as Tungsten Carbide or Silicon Carbide) to ensure longevity.
3. What material should I choose for corrosive environments?
While 316SS is our standard, we offer Duplex Steel and Titanium options for plants dealing with aggressive chemical bleaching processes or high-chloride environments.
4. How does the stationary design benefit my pressure screen?
Stationary seals are generally better at handling shaft misalignment and high speeds compared to rotary seals. In a vertical screen like the Ultra-V™, this leads to more stable performance and less wear on the internal components.
5. Which piping plans are most common for this seal?
For the KADANT® UV applications, we frequently see Plans 11 or 32 being used to ensure proper cooling and lubrication of the seal faces, though the 2550 Series is compatible with a wide range of API piping plans.
