Type 3740D
Dry Running Cartridge Split Seal
The Type 3740D dry-running split seal is a mechanical seal designed for the large shaft run-out and harsh operating conditions commonly associated with top-entry vessel mixing services and other dry-running applications. Type 3740D dry-running split seals are suitable for use in equipment according to 2014/34/EU (ATEX 95) Group II, Category 2 GD.
The Type 3740D is part of the 3740 Series of split seals, which includes the Type 3740 wet-running split seal. These split seals use the latest modular split seal technology from John Crane that combines the unique design requirements for wet-running and dry-running services onto one common seal platform.
