Universal Cartridge Seal Family — Dual Cartridge O-ring Seal – is5620 – is5620P

The first truly universal cartridge seal, the is5620/5620P will change your approach to sealing. Since the is5600 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 .

Technical Description

Product Description is5620 – is5620P

The is5600 Series is a modular cartridge seal family that includes interchangeable elastomer bellows, metal bellows, and elastomer O-ring pusher seal designs.

Dual seal arrangements incorporate an elastomer O-ring as the dynamic secondary sealing member.
Primary and mating ring reverse balance designs allow for ID or OD pressurization, which permits the dual seal to operate as a tandem or double.
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

Applications

Process pumps
Other rotating equipment

California Residents: PROPOSITION 65 WARNING
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.
is5620P comes standard with a pumping ring.
