Mechanical Seals

From improving product modularity to meeting changing emissions standards, we’re constantly developing new solutions and improving on our best designs to offer our customers superior dependability.

Today, our durable, versatile Type 28 non-contacting gas seals boast more than 750 million combined hours of operation, and our Type 2800 Series mechanical seals offer superior containment of fugitive emissions.

The problem-solving nature of innovation often manifests as improvements to existing solutions. This is particularly evident in our redesign of the traditional API 682 water cooler, the vertical design of which made venting difficult.

By re-engineering the water cooler to include a horizontal cooling coil instead, John Crane was able to increase the reliable operation of water-cooled heat exchanger units.
