Equipment including Flexaseal's unique modular slurry seal design is oriented to be immediately behind the impeller, optimizing available space as well as minimizing abrasive wear on the rotating sleeve. With four (4) configuration options all incorporating additional engineered features such as reverse pressure capability, non-clogging multi-springs, rugged seal drive operation, and hydraulically balanced faces, the RKCS single and RKCD dual seals successfully contend with the industry's toughest slurry challenges.
