Flygt Plug-In 25mm Seal Kit — Double Cartridge Mechanical Seal

The Flygt plug-in 25mm seal kit is a replacement pre-assembled double cartridge mechanical seal for Flygt/Xylem submersible pumps and mixers built on a 25mm shaft. The plug-in design holds the motor-side and liquid-side seals in a single aligned unit, which shortens rebuild time and delivers repeatable sealing performance compared with fitting loose component seals.
