Type 3740XL

Extra Large Wet Running Cartridge Split Seal

The Type 3740XL wet-running split seal is the extra large version of John Crane's successful Type 3740 split seal that incorporates proven mechanical seal design features for fast and easy seal installation, while providing reliable seal performance in demanding large pump and other big rotating equipment fluid services.

Type 3740XL split seals are especially beneficial for use on large pumps and rotating equipment that are difficult and time consuming to disassemble for non-split seal installations & repairs or packing maintenance. These mechanical seals are commonly used in desalination, irrigation, mineral processing, power generation, pulp & paper and water/wastewater industries.
