Type 2800EX gas lubricated, noncontacting seals are fitted with an excluder that reduces solids within the seal chamber. The product is capable of handling up to 28% solids. An inert barrier gas is injected into the barrier chamber and a spiral grooved pattern on one sealing face pumps gas toward the ungrooved portion of the face, preventing contact and wear.
