Mechanical seals are most commonly used where it is important to retain the working or process fluid and also prevent the ingress of abrasive particles.
For these reasons mechanical seals are most commonly found on applications like military vehicles, off road vehicles and mining machinery
Mechanical seals consist of two lapped cast rings forming a dynamic rotary seal with two O rings forming static seals on their outer diameters. They are commonly found on off road equipment, military tracked vehicles and mining equipment.
