STRUCTURE DESCRIPTION
Replacement of John Crane 5610. Single cartridge mechanical seal.
Features:
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.
