Type 285 Dry Gas Seals John Crane Metal Bellows Mechanical Seal For Cryogenic Pumps

Thinking about an upgrade for your cryogenic pump sealing? In this video, we demonstrate the John Crane Type 285 Dry Gas Seal in action. You'll see how its unique spiral groove technology creates a non-contacting gas film to eliminate face wear and dry-running issues common with conventional seals. We walk through its key features, safety compliance for liquid oxygen applications, and explain how it extends maintenance intervals while sealing liquefied gases like nitrogen, oxygen, and argon.
