PTFE Bellows | Pump Seals | John Crane


John Crane’s PTFE bellows seals offer a solution where all process wetted seal materials are chemically inert. Metal components, springs and the clamp ring are located outside the pump seal chamber, isolated from the process fluid. Used for extremely corrosive chemicals, including acids, caustics and chemically active organic compounds. This allows a safe, cost-effective solution without the need for expensive metal alloys.
