Flexaseal
Slurry Seals
Flushless Slurry Seals Built for the Toughest Pumping Environments
Flexaseal’s RKC Series slurry mechanical seals are engineered to perform under the most punishing conditions found in mining, mineral processing, flue gas desulfurization (FGD), and other abrasive, high-solids applications. Designed for durability and efficiency, these heavy-duty seals deliver long-lasting reliability, without the need for external flushing.
The RKCS single cartridge seal and RKCD dual cartridge seal are easy to maintain and built to handle extreme operating conditions. Available in four unique configurations, each model incorporates robust features like reverse pressure sealing, non-clogging spring designs, and hydraulically balanced seal faces, ensuring consistent performance in highly abrasive and corrosive environments.
