Proven in applications around the world, this split seal design greatly enhances reliability by keeping water and contaminants out of the hub and keeping lubricants in to avoid environmental contamination.
Chesterton’s Kaplan Runner Blade Trunnion Split Seal has a pin and lock design that keeps the turbine motion from pulling the split seal apart and also uses load pressure to join cut ends.
Unlike standard stack sets, these seals are designed with a positive, flared lip design which enables them to automatically adjust and compensate for radial cross sectional variances. This feature helps resist blade droop which so often causes reliability issues.
