DO Type

The DO type is the most used mechanical face seal type, which consists of two identical metal rings and two elastomer O-rings. This compact mechanical seal is primarily intended for constant low speed, heavy load application. High wear resistance, automatic compensation telescopic after the end face has wear, reliable operation, compact structure, and low maintenance are the advantages of using this type of seal.

Duo cone seals are widely used in many types of machinery operations, e.g. coal mining machinery and machinery used in infrastructure, including bulldozers, scraper conveyor head (tail) sprocket assemblies, and tunnel boring machines.

Operating Principles and Longevity of Do Type Duo Cone Seals

The rotation of the shaft also causes the sealing ring that encompasses it to rotate while the second sealing ring remains unchanged. The rotational torque means that axial pressure acts automatically on the sealing ring interface, which increases the sealing efficiency by pushing out any contaminants and fluids. As a result, one sealing ring rotates in relation to the other, and the O-rings are compressed against each other, which establishes a sealing force across the two sealing faces.

The sealing faces are continually held in contact with one another, so dirt, sewage, and other contaminants cannot enter from the outside world. As the sealing faces wear evenly over time, the O-rings release their stored elastic energ. These provide axial compensation while keeping the duo cone seal effective for as long as possible. The typical service life goes up to 5000 hours.
