White Knight Tongue-and-Groove Seals are the most reliable and re-useable sealing technology available in high-purity pumps.

The seals are machined into mated pump parts that act as barriers to liquid leaks. They are designed so that the tongues expand diametrically within the grooves to create an interference fit which provides reliable, effect sealing. The machined design provides more effective seals than molded seals because machining allows for tighter tolerances than molding processes.
