OD FACE SEALS
End face mechanical seals, or mechanical face seals, are utilized in rotating equipment, such as pumps and compressors. When a pump operates, the liquid can leak out between the rotating shaft and the stationary pump casing. Preventing this leakage can be difficult since the shaft rotates. An end face mechanical seal uses both flexible and rigid elements that maintain contact at a sealing interface and slide on each other, allowing a rotating element to pass through a sealed case. The elements are both hydraulically and mechanically loaded with a spring or other device to maintain contact.
