The advantages of Cartridge type mechanical seals：
The cartridge type mechanical seal is a combination of all components of the mechanical seal such as rotary face ring, stationary seat ring, spring, second seal ,sleeve and gland.It can be assembled and disassembled when needed. According to relevant statistics, the installation failure rate of ordinary component mechanical seals is much higher than that of cartridge mechanical seals. Therefore, the use of the cartridge mechanical seal structure can greatly reduce the occurrence of mechanical seal failure. Since the cartridge type mechanical seal does not require any adjustment of the mechanical seal by the installer (such as springs, sealing surfaces, etc.), it is only necessary to tighten the bolts, thereby greatly improving the reliability of the mechanical seal installation.

Cartridge mechanical seals have the following advantages:
1, ready-to-install components include rotating components, bushings and glands;
2, the installation is simple, less installation error;
3, the gland of the gland bolt is suitable for most stuffing boxes;
4, easy to replace the packing or bearing seal;
5, easy to remove, easy to carry out off-site renovation;
6, easy to install in some places that are not easy to install!
