Reliable Non Cartridge Mechanical Seal Design and Its Use in Standard Pump Applications

The non-cartridge mechanical seal construction consists of separate seal components that installed directly on the shaft upon installation. The no-cartridge mechanical seal construction allows for architectural and economical flexibility for standard mechanical sealing applications. Non-cartridge mechanical seals require more attention during installation as compared to cartridge seals; however, non-cartridge seals are commonly used across the global marketplace since they provide compatibility with most common industrial pump specifications.

Non Cartridge Mechanical Seal: Pressures and Pump Types

Non cartridge 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 Seal(s) hinges on pressure and temperature conditions, so balanced seal(s) are specified based on operating conditions including pressure.
Yes, in most instances - if proper selection and installation methods are followed.
