In the demanding environments of pulp and paper, sugar, and chemical processing, Andritz ACP series centrifugal pumps are industry workhorses. Maintaining their reliability depends heavily on the integrity of the mechanical seals. When it comes to seal replacement, finding high-quality alternatives that match OEM specifications while offering better lead times is a top priority for plant managers. At FBU, we have engineered specialized cartridge seals—the 2233 and 2234 series—designed specifically to be 100% interchangeable with Andritz/Sulzer JCS1C and JCS2A seals.   Read More>

In the demanding environment of pulp and paper manufacturing, mechanical seals are the unsung heroes of operational uptime. Unlike standard chemical processing, the pulp and paper industry presents a unique "triad of destruction": high solids content (slurry), aggressive chemical cleaning (CIP), and extreme temperature fluctuations.   Read More>

In the demanding environment of pulp and paper mills, pump reliability is dictated by the performance of its seal. For those operating Sulzer® APP, APT, or NPP series centrifugal pumps, finding a seal that can handle high-stock consistency without the premium OEM price tag is a constant challenge.FB   Read More>

In the high-stakes environment of petrochemical refining, the cost of a mechanical seal is negligible compared to the cost of its failure. Yet, a recurring frustration for maintenance and reliability engineers isn’t necessarily the design of the seal itself, but the inconsistency of quality between   Read More>

In the petroleum and petrochemical industry, centrifugal pumps are the backbone dynamic equipment across the full production chain — spanning upstream oil and gas exploration and gathering, midstream refining and processing, to downstream storage and distribution. Mechanical seals, in turn, stand as   Read More>
