Inboard pump seals:

The term Inboard seals simply refers to seals that are mounted inside of a pumps stuffing box, to a shaft or sleeve and are mounted independently as individual parts. Unlike Cartridge seals which is a unitized set of rotating, stationary, sleeve and gland components. Inboard seals are mounted to an existing sleeve or shaft. The stationary the inboard seal runs against is independently press fit (usually), into a bore and can be purchased separately from the inboard seal.

Inboard Mechanical seals

 

Inboard seals can be any of the following

* Single Spring Seals ASP Type 21 Single Spring Pump Seal
* Multiple Spring Seals ASP TYPE 60 Pump Seals
* Metal Bellows Seals MBFG Metal Bellows Pump Seal
* Wave Spring Seals Wave Spring Pump Seal

If it is mounted inside of the stuffing box, has a method of energizing one face against another (such as a bellows, or spring) and is mounted to the shaft independently of the stationary face it qualifies as an inboard seal.

Inboard seals are the least expensive approach to installing pump seals into pumps.  They are also the most difficult to install.  It is critical the that during the installation process seal length is carefully calculated to obtain the correct positioning of the seal on the shaft.  The position of the stationary face must be taken into consideration. Over compression of the seal face will result in premature wear,  insufficient compression will result in leakage.
