The Type 261 is a single-end cartridge mechanical seal for slurry pumps and side entry mixers. It features a multiple-spring design and an unbalanced sealing structure.
The cartridge design simplifies installation and replacement. Its independent rotation capability allows operation in either direction.
An internal bearing kit supports stable operation under demanding slurry conditions. Two framework oil seals protect the internal bearing assembly from the process environment.
The multiple springs remain separated from the process medium. This helps reduce the risk of clogging caused by slurry particles and deposits.
The Type 261 complies with API 682 and provides reliable sealing performance in abrasive and corrosive applications. It is mainly used for slurry pumps and side entry mixers.
