Agitator / Reactor Mechanical Seal

Double Balance/Unbalance Gas Lubricated Agitator/Reactor seal

In mixing technology, the sealing of a rotating agitator shaft in the passage through a vessel wall represents the principal sealing task. Different sealing principles are used depending on operating conditions such as pressure, temperature, and speed. Most mechanical seals of agitators consist of gland plate with Mating ring and sleeve with seal ring and elastomeres for leakage prevention. They are usually top,bottom and side mounted on the vessel.

In Dry gas or gas lubricated agitator seal grooves are machined into the mating ring faces. Then pressurized gas is injected between the seals. As the shaft rotates, gas flows into the tip of the groove and which in return distances the faces creating thin film of gas for small amount ranging in micron. thus separating the faces. This seal continues to operate, even if barrier gas pressure is momentarily lost, maintaining the gas film between the barrier gas and the process.
