Manufacturer: John Crane

Universal Cartridge Seal Family - Dual Cartridge O ring Seal

The first truly universal cartridge seal, the Type 5620/5620P 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 available conform to API 682, Category 1.

• Incorporates an elastomer O ring as the secondary sealing member.

• Primary ring and mating ring reverse balance designs allow for ID or OD pressurization, which permits the dual seal to operate as a low pressure barrier tandem seal or a high pressure barrier double seal.

• OD pressurization of the outboard seal avoids subjecting components to high tensile stresses and achieves improved cooling. On vertical installations, it allows venting of entrapped air.

• Reversible seal head.

• Non clogging wave spring outside the product; fits ANSI and ISO seal chambers.

• Optimized primary ring design for greater reliability.

• Set screwless outboard seal drive.

• Tangential inlet and outlet pipe connections below 3.000"/75mm.

• Type 5620P comes standard with a pumping ring.
