The Type 3740 wet-running seals allow easy installation while providing reliable performance in demanding pump and other rotating equipment fluid services. The Type 3740D dry-running split seal is designed for the large shaft run-out and harsh operating conditions associated with top-entry vessel mixing services and other dry-running applications. Typical wet-running applications include pumps and side-entry agitators, while the dry-running version is for top-entry mixers and other dry environment sealing.

The new seal family allows fast and easy installation, even by those with minimal split seal training and installation skills. It also ensures a long and reliable service life. The Type 3740’s robust capabilities also allow more difficult services to be sealed with a split seal than ever before. The Type 3740 wet-running seal can successfully operate in applications  up to 450 psig and withstand shaft run-outs of up to 0.060-inches TIR, while the Type 3740D dry-running version can accommodate pressures from vacuum conditions up to 80 psig and shaft run-outs of up to 0.150-inches TIR.
