About Mechanical seal type 5615

The 5600 Series is the first truly universal cartridge seal — and the modular family concept of John Crane’s Universal Cartridge will change your approach to sealing. Since the 5600 Series’ components are interchangeable, you can apply one seal family throughout your plant. This gives you the flexibility to cover more applications with less inventory, which means your maintenance is simplified, downtime is reduced, plant operating efficiency is increased and costs are lowered. The 5615 is available with either Alloy 20 or Alloy C-276 edge-welded metal bellows in either a rotating or stationary configuration.
