Non-contacting mechanical seals operate with inert gas as a seal face lubricant. They provide a highly durable mechanical seal for demanding refinery and chemical processing applications. Non-contacting sealing technology can also be used to preserve product purity.
John Crane non-contacting mechanical seals can assist companies who are seeking a zero-emission/zero leakage mechanical seal solution to achieve environmental and safety regulations.
