Mechanical seals come in different configurations, and each variant has its advantages and disadvantages. Among the most common variants are component mechanical seals and cartridge mechanical seals.
When selecting a mechanical seal type, pump users must consider the cost of installation, long term running costs, pump characteristics, and the anticipated operational conditions (heat, vibration, and pressure). Keep your technical staff in mind as well, because having a skilled technician on-hand for regular maintenance vs. having to outsource maintenance and repairs makes a significant difference.
A cartridge mechanical seal is a completely enclosed seal system with preassembled components. Typically, this seal type is composed of a gland, sleeve, and other hardware that make pre-assembly possible.
Component mechanical seals are composed of separate dynamic and stationary parts. Unlike cartridge seals, component seals are not preassembled and require skilled technicians to install them. Incorrect installation of seal faces, O-rings, and seal axial setting on the pump shaft will result in reduced seal life or in some cases, immediate seal failure.
The major cons for non-cartridge mechanical seals are their susceptibility to damage. Other than cartridge type seals that are completely encased within secure housings, component mechanical seals usually have exposed parts that are more susceptible to damage during transportation or installation.
Further, non-cartridge type seals require precise measurements during installation to prevent seal failure. Properly installing this type of seal requires more operator time and thus a higher cost to install or re-install after a repair.
