Wet- and dryrunning on one seal platform

John Crane has launched a sealing solution that meets the requirements for wet-running and dry-running capabilities with one common seal platform. The new Type 3740 cartridge split seal (the latest addition to the company's split seal portfolio) is available in two variations - the Type 3740 for wetrunning and the Type 3740D for dry-running services. Easy to install, Type 3740 wetrunning seals offer reliable performance in demanding pump and rotating equipment fluid services. The Type 3740D dryrunning split seal is designed for the large shaft run-out and harsh operating conditions commonly associated with top-entry vessel mixing services and similar dryrunning applications.

Typical wet-running equipment applications include pumps and side-entry agitators, while the dryrunning version is for top-entry mixers and other dry environment sealing services that frequently have large levels of shaft run-out.
