Component or Cartridge: How to Choose the Right Seal
Mechanical seals consist of a rotating element and a stationary element, each with a lapped, precision-smooth mating face. Seal performance is determined primarily by the condition of the faces and the pressure applied to them. Other key factors are vibration, heat and pumpage characteristics. Depending on the application and user's needs, different seal types may be appropriate.
For many larger centrifugal pumps, users have the option of installing either component or cartridge mechanical seals. Understanding the advantages and limitations of each can help determine the best solution for a particular application.
