DESCRIPTION

Flygt Plug-In 90mm Seal Kit — Double Cartridge Mechanical Seal

The Flygt plug-in 90mm seal kit is a replacement pre-assembled double cartridge mechanical seal for Flygt/Xylem submersible pumps built on a 90mm shaft. The plug-in design holds the motor-side and liquid-side seals in a single aligned unit, built to OEM-equivalent standards or higher. The Flygt 3301 and 3315 are N-technology submersible wastewater pumps used in municipal sewage, stormwater and industrial wastewater service. The Flygt 5150.350 and 5150.360 are abrasion-resistant submersible slurry pumps used for sand, grit, ash and sludge duty. All four share the 90 mm plug-in cartridge seal covered by this kit.
