(Type CD43)

Dual Cartridge Seals is a factory assembled cartridge unit specially design for slurry & viscous media.Double Cartridge Seal is a self contained unit consisting two mechanical seals in a seal chamber in any combination which can utilize a pressurized barrier fluid or a non pressurized buffer fluid.

These seal arrangements are a superior upgrade to a single cartridge Seals when it is imperative the media does not leak to atmosphere. A dual cartridge seal very often is formed with tandem configuration (face-to-back), or face-to-face configuration.

In a tandem configuration, the outer seal essentially works as backup for the primary a face-to-face arrangment,the outer seals creates a barrier. When any issue happens with the inner seal.
