John Crane Mechanical Seals - Type 5610 Cartridge Seal


The John Crane  5600 series components are cartridge-style mechanical seals designed for use in seal chambers conforming to ANSI B73.1M, ISO 3069, and DIN 24960 standards. These robust seals provide reliable shaft sealing across various pump applications.

The versatile 5610 seals have a modular design with interchangeable components. The standard arrangements utilize an elastomer O-ring as the secondary sealing member. The common seal head and mating ring components are reversible, allowing for rotating seat or rotating head configurations. The 5610 can be enhanced with a quench gland that utilizes a lip seal (5610L) or a carbon ring throttle bushing (5610Q) to suit processing conditions.
