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.

In the demanding environment of chemical processing, the reliability of fluid handling equipment hinges on one critical component: the mechanical seal. A single seal failure can lead to costly downtime, safety hazards, and environmental compliance issues.
While seal design is vital, material science is often the deciding factor between a leak-free operation and catastrophic failure. This guide provides a technical framework for matching seal faces and elastomers to aggressive chemical media, with a specific focus on the complexities of sulfuric acid (H2​SO4).

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

In the Pulp & Paper and Mining industries, pump mechanical seal failures account for over 60% of unscheduled downtime. If you are tired of replacing seals every 3 months on your slurry pumps, you are not alone.While many engineers blame "bad seal quality," the reality is often found in the operating

The Invisible Enemy of Mechanical SealsYou’ve invested in a high-quality single cartridge mechanical seal, followed the installation manual to the letter, and ensured your API flushing plan is operational. Yet, within weeks—or even days—the seal begins to leak.When you strip the pump, the faces are
