Clark Seals, was approached by the largest manufacturer of commercial laundry equipment to address a seal leakage issue in sandy environments. Sand particles were entering between the sealing surfaces of the mechanical seal, causing face grooving and resulting in leakage.

To resolve the problem, we designed a custom two-piece integrated sealing solution that sealed both the top and bottom of the tub. The top seal was engineered to press-fit around the tub bearing, improving alignment between the transmission, tub, and agitator, while featuring a triple sealing lip to prevent water, sand, and debris from entering the bearing cavity. The bottom seal was designed with a locking pin to resist torque and press-fit into the top seal during installation. To further combat the intrusion of sand and contaminants, our engineers developed and patented a unique negative "R" sealing lip geometry. This innovative design allowed the sprung lip to function as an excluder lip, effectively keeping all sand and debris out of the sealing environment.

The result was a patented sealing solution that eliminated warranty claims, reduced costs by 80%, and lasted more than 700% longer than the original mechanical seal it replaced.
