OD FACE SEALS

An end face mechanical seal or mechanical face seal is a type of seal utilized in rotating equipment, such as pumps and compressors. When a pump operates, the liquid can leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this leakage can be difficult. An end face mechanical seal uses both rigid and flexible 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.
