Regardless of the considerations, when the pressure of the stuffing box exceeds 50psi, it is generally recommended to use a balanced mechanical seal.

Cartridge type mechanical seal

The cartridge seal is an all-in-one sealing device, which contains all sealing elements, glands and shaft sleeves. Since this type of seal does not require any strict installation measures, the installation procedure is greatly simplified, and the sealing surface and sealing elastomer are well protected from accidental damage. These benefits also mean less time for seal repair and replacement.

Almost all kinds of cartridge seals can be purchased in the market, so the risk factor in use can be reduced, and the maintenance time inherent in the use of ordinary seals can also be saved.
