Balanced vs Unbalanced Sealing Designs: How They Differ and What Types of Applications You Would Use Each Type

One of the main areas that balanced and unbalanced seals differ from one another is in their hydraulic pressure distribution over the rand sealing face surfaces. Because they can better work with the face loadings on the sealing faces, balanced seals tend to be a preferred choice when used at high pressures; whereas unbalanced seals generally are constructed in a simpler manner and may be utilized in standard applications. A clear differentiation between balanced and unbalanced seals will allow you to properly select the seal structure to meet the operational and reliability requirements of your system.

Balanced Vs Unbalanced Mechanical Seals: Pressures and Pump Types

Both balanced and unbalanced mechanical seals are installed based on pressure conditions and pump configuration. Most standard industrial pumps that are operated under medium pressure operating conditions are commonly installed with non-cartridge mechanical seals due to their compact construction, as well as their ease of sealing installation. Non-cartridge mechanical seals generate a large majority of the usages of these types of Sealing methods. The majority of non-cartridge seals are used in the industrial pumping, utility, and factory operations because of their ability to work with operational consistency vs specialized sealing requirements.

FAQ

How Do Balanced Seal Differ From Unbalanced Seal?

Balanced Seal reduce the load on the seal faces, while Unbalanced Seal have a more straightforward structure.
The decision whether to use balanced Seals hinges on pressure and temperature conditions, so balanced seals are specified based on operating conditions including pressure.
Yes, in most instances - if proper selection and installation methods are followed.
