Type 5611Q

Universal Cartridge™ Seal Family — Single Cartridge Elastomer Bellows Seal with Quench

The Type 5611Q mechanical seal is part of the 5600 universal cartridge seal family — and the modular 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. Designs are available that conform to API 682, Category 1.
