- 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.
